Washington Redskins wide receiver Taylor Jacobs was among the Washington Redskins players making their 2005 debut in Monday night's game against the Dallas Cowboys. Jacobs missed the season opener, a 9-7 victory over the Chicago Bears last week, because of a toe injury.

Jacobs was activated for the first time since the 2004 regular season finale. He hadn't played in the preseason because of a fractured big toe. Jacobs suffered the injury in an August 6 scrimmage against the Baltimore Ravens at M&T Bank Stadium. Jacobs didn't participate in another practice until Sept 5. He had felt healthy enough to play last week but wasn't activated by Coach Joe Gibbs.

Jacobs's return is significant since the Redskins have only four receivers on the roster after releasing kick returner Antonio Brown last week. Brown had been Washington's fifth receiver in a part-time role. The Redskins filled Brown's roster spot with kicker Nick Novak, who made his NFL debut, because John Hall suffered a quadriceps injury last week.

After being picked 44th overall in the 2003 draft, Jacobs performed well during his rookie preseason. But in the preseason finale, Jacobs suffered an abdominal injury that plagued him early in the season. Jacobs was inactive for the first three games before making his NFL debut Sept. 28 against the New England Patriots. He finished his rookie season playing eight games.

Last year, he suffered an injury during training camp that caused him to miss the season opener. But he appeared in 15 games while starting four times.

Outside linebacker Chris Clemons also was activated for the first time this season. Clemons strained his hamstring the week leading to the season opener and was forced to sit. After showing promise late last season, Clemons is expected to provide the Redskins with pass rushing. Clemons wasn't signed until Nov. 24, when he was activated from the practice squad. In only six games, Clemons collected three sacks, nine tackles (six solo) and a forced fumble. (Clemons's brother, Nic, had a strong preseason to make the roster as the backup to left defensive end Renaldo Wynn.)

Clark Still Sidelined

Strong safety Ryan Clark, who was on the first unit for most of preseason, missed his second straight game because he isn't fully recovered from a left knee strain. Monday night, Pierson Prioleau started again next to free safety Sean Taylor, with Matt Bowen coming off the bench. But Prioleau suffered a pulled hamstring about five minutes into the game and did not return.

During preseason, Bowen was considered Clark's competition for the starter's role. But Bowen suffered a right knee injury and then a bruised chest, and isn't 100 percent healthy. . . .

Hall was deactivated as expected. During the week, Gibbs said it was unlikely Hall would be able to kick, although the Redskins didn't officially rule Hall out. He was downgraded to doubtful Friday after being questionable for most of the week.

The rest of Washington's inactives were tailback Nehemiah Broughton, rookie linebacker Zak Keasey, offensive lineman Jim Molinaro, defensive tackle Brandon Noble and Clemons. Rookie Jason Campbell was Washington's third quarterback. The Cowboys inactives were tailback Marion Barber, fullback Lousaka Polite, linebacker Kevin Burnett, guard Ben Noll, defensive end Jay Ratliff, guard Stephen Peterman and defensive tackle Thomas Johnson.

Oldies but Goodies

The Cowboys donned throwbacks jerseys from the 1960s. During a halftime ceremony at Texas Stadium, Dallas's "Triplets" were inducted into the club's Ring of Honor: Quarterback Troy Aikman, wide receiver Michael Irvin and tailback Emmitt Smith helped the franchise win three Super Bowls in four years. Their inductions to Dallas's Ring of Honor brings the total to 15. . . .

Right tackle Jon Jansen made his debut of sorts -- with two broken thumbs, wearing soft casts he is expected to be in for the next few weeks. Jansen broke his left thumb in a Sept. 5 practice and then his right thumb against Chicago. Monday night, Jansen matched up against left defensive end Kenyon Coleman, a fourth-year veteran who made only his second career start. In Dallas's season-opening victory over the San Diego Chargers last week, Coleman made his NFL starting debut, recording two tackles
