Who, No. 5 Texas A&M might ask, is Sammy Morris?

For the record, he's a reserve running back with little playing time since 1996 because of academic problems. Last night, he was a Ricky Williams look-alike, running for 170 yards in pacing Texas Tech (2-2, 1-0 Big 12) to an improbable 21-19 victory over the Aggies in Lubbock, Tex.

"Coach told me to be prepared to get a lot of carries," Morris said while watching students tear down the goal posts. "I was getting a lot of reps in practice, but I didn't think I would get that many carries (33)."

Morris wasn't even mentioned by Coach Spike Dykes in the week leading up to the game as a possible replacement for Williams, who is out for the season with a knee injury after running for 1,582 yards last season.

"Sammy Morris had a great running effort," Aggies linebacker Jason Glen said. "We weren't prepared for him. Leave it to Tech to get a backup to run like an all-star."

Down 21-10 at the half, Texas A&M (3-1, 0-1) inched back on the foot of Terence Kitchens, whose four field goals included two in the third quarter and another with 8 minutes 15 seconds to play.

With the Aggies again driving and needing only a field goal, Tech's Dorian Pitts sacked quarterback Randy McCown, whose pass on the next play was intercepted by Antwan Alexander with 1:28 to play.

"Tech's defense did a great job of holding us out of range," McCown said. "It definitely hurts, but we've got to bounce back. This is just a reality check."

NOTRE DAME 34, OKLAHOMA 30: Jarious Jackson is the heart and soul of the Irish. Against Oklahoma, he finally gave them the heart to win.

Jackson threw for two touchdowns and ran for one in leading Notre Dame to 20 consecutive second-half points and the upset of No. 23 Oklahoma in South Bend, Ind. It was Notre Dame's biggest comeback win in 13 years.

"I said we've got to get this victory," Jackson said. "I said if I have to put an IV in my arm after the game, we're going to get this victory."

Josh Heupel hit Brandon Daniels for a 15-yard touchdown pass to give Oklahoma (3-1) a 30-14 lead with 10:01 left in the third quarter, and the Irish looked whipped. But Jackson hit Jabari Holloway for a 15-yard touchdown with 7:20 left in the third to begin the comeback. After Lee Lafayette intercepted Heupel's pass at the Irish 44, Jackson led Notre Dame down to the 1-yard line, where Tony Driver punched it in to pull the Irish to 30-28 with 2:37 left in the quarter.

Jackson wasn't finished, leading Notre Dame on its most impressive drive of the season.

The Sooners downed Jeff Ferguson's punt at the 2-yard line with 14:45 left. Runs by Driver and Tony Fisher gave Notre Dame some running room, and five plays later Jackson scrambled for 23 yards, showing no signs of the turf-toe injury that has hampered him the last four weeks.

FLORIDA ST. 51, DUKE 23: A week after getting 28 points at North Carolina in the first quarter, the top-ranked Seminoles rolled up a 44-0 halftime lead on their way to a victory over winless Duke in Jacksonville, Fla.

Chris Weinke threw five touchdown passes, three to Peter Warrick, to lead an offense that is averaging 43.2 points per game.

Florida State (5-0, 4-0 Atlantic Coast Conference) scored on all eight of its first-half possessions as Seminoles Coach Bobby Bowden picked up his 297th career victory.

GEORGIA 23, LSU 22: In Athens, Ga., the 10th-ranked Bulldogs escaped with a one-point victory for the second week in a row. LSU scored with 18 seconds remaining and went for the win, only to see Will Witherspoon bat away Josh Booty's two-point conversion pass to preserve Georgia's unbeaten record four games into the season.

Booty, who bypassed college to spend five years in minor league baseball, almost made his first college start memorable.

With LSU trailing 23-16, Booty steered the Tigers from their 39 to the Georgia 28 before having a pass picked off in the end zone by Cory Robinson with 1:55 remaining.

Georgia (4-0, 2-0 Southeastern Conference) was unable to run out the clock and LSU (2-2, 0-2) got the ball back at its 39 with 1:26 to play. Booty hit Ed Dangerfield with a 32-yard pass on the Georgia 39. After three incompletions, he found Reggie Robinson at the goal line for the touchdown with 18 seconds to play.

On the two-point play, Booty rolled to the right sideline, dodged a defender and tried to hit either of two open receivers on the far side of the field, but Witherspoon made a leaping deflection to save the Bulldogs.

KENTUCKY 31, ARKANSAS 20: Dusty Bonner threw four touchdowns, two to Quentin McCord, as the Wildcats built a 21-0 first-half lead and held on to upset the 20th-ranked Razorbacks in Lexington, Ky. It was the Wildcats' biggest win over a top 25 opponent since a 21-0 home victory over Mississippi in 1993.

Kentucky (3-2, 1-1 SEC) dominated Arkansas (2-2, 0-2), limiting the Razorbacks to 97 rushing yards. The Wildcats had two interceptions, recovered a fumble and blocked a field-goal attempt by Razorbacks place kicker Tony Dodson.

NEBRASKA 38, OKLA. ST. 14: Eric Crouch threw for 145 yards and a touchdown and ran for a score as the No. 6 Cornhuskers prevailed in Lincoln, Neb.

Crouch, who was 7 for 13, also gained 61 yards on 11 carries and Correll Buckhalter ran for two touchdowns for Nebraska (5-0, 2-0 Big 12), which extended its unbeaten streak over Oklahoma State to 36 games.

The Cornhuskers haven't lost to Oklahoma State since 1961.

TENNESSEE 24, AUBURN 0: In Knoxville, Tenn., Deon Grant's interception return for a touchdown on the game's first play started the No. 7 Volunteers to their first shutout of Auburn since 1980.

The Volunteers (3-1, 1-1 SEC) once again struggled on offense, but the defense would not yield to the Tigers (3-2, 1-2) with redshirt freshman Jeff Klein making his first start at quarterback.

Travis Henry scored on runs of 34 and one yard to provide some offensive punch for the Vols, who gained 401 yards but came up empty on five trips inside the Auburn 23.

MICHIGAN ST. 49, IOWA 3: Bill Burke threw four touchdown passes and Plaxico Burress caught three scoring strikes in the first half to lead the 14th-ranked Spartans to a rout of the Hawkeyes in East Lansing, Mich.

Michigan State (5-0, 2-0 Big Ten) moved almost at will against the Hawkeyes, as its balanced ground and passing games built a 35-0 halftime lead. Iowa (1-3, 0-1) had little luck moving the ball against the Spartans, who have not given up a touchdown on the ground this season.

MISSISSIPPI ST. 42, VANDERBILT 14: In Nashville, the No. 16 Bulldogs (5-0, 2-0 SEC) had six sacks and forced three turnovers in routing Vanderbilt to ensure their best start since 1944.

The Commodores didn't help themselves as quarterback Greg Zolman fumbled the snap on the first play from scrimmage and Alvin McKinney recovered. Four plays later, Rod Gibson scored from three yards for a 6-0 lead, and the Bulldogs never looked back.

MARSHALL 32, MIAMI (OHIO) 14: Chad Pennington threw for 294 yards and three touchdowns to lead the 17th-ranked Thundering Herd in Oxford, Ohio.

Marshall (5-0, 2-0 Mid-American Conference) dominated a game billed as a showdown between the league's best teams. The Thundering Herd rolled to a 32-0 lead before allowing two late scores by Miami (3-2, 2-1).

Pennington was 18 of 35 without an interception.

SYRACUSE 47, TULANE 17: Madei Williams hit Pat Woodcock with a 22-yard touchdown pass and Nate Trout kicked a 37-field goal in the final minute of the first half to break open a tight game and help lead the No. 22 Orangemen to the win over the Green Wave at the Carrier Dome.

Syracuse (4-1) also converted three interceptions into 13 points in the first half to thwart the high-powered attack of Tulane (2-2) and its sophomore quarterback, Patrick Ramsey.

EAST CAROLINA 33, ARMY 14: With all Hurricanes finally aside, No. 19 East Carolina kept generating its own little storm by rolling past Army in West Point, N.Y., to move to its best start since 1976.

David Garrard threw for 300 yards, including a 62-yard touchdown pass to wide receiver Arnie Powell, and the Pirates (5-0), coming off a comeback victory over Miami, added fourth-quarter touchdowns on a 40-yard fumble return and a 46-yard return of an onside kick.

KANSAS ST. 35, TEXAS 17: David Allen returned a punt for a record-tying touchdown and also ran for a score as No. 13 Kansas State capitalized on six turnovers by Texas quarterback Major Applewhite for the win over the 15th-ranked Longhorns (4-2, 1-1) in Austin.

Jamie Rheem kicked a school-record five field goals for Kansas State (4-0, 2-0 Big 12), which converted three interceptions and three fumbles by Applewhite into 26 points.

Allen's 74-yard return in the third quarter gave Kansas State a 15-14 lead and gave him seven touchdown returns for his career, tying the NCAA Division I-A record set by Oklahoma's Jack Mitchell (1946-48) and matched by Nebraska's Johnny Rodgers (1970-72).
