The injured left knee of Jacksonville Jaguars quarterback Byron Leftwich is to be re-examined by doctors on Monday and a determination will be made then whether surgery is required and how long Leftwich would be sidelined, according to the team.

Jaguars officials said after a preliminary examination of Leftwich's knee by Birmingham orthopedic specialist James Andrews on Tuesday that they did not think surgery was needed. The initial diagnosis was that Leftwich had a sprained lateral collateral ligament that could keep him sidelined as long as four to six weeks but perhaps could heal more quickly and enable him to play sooner -- even as soon as the Jaguars' next game, against the Detroit Lions on Nov. 14. Jacksonville has a bye this week.

It appears increasingly likely, though, that backup David Garrard will be Jacksonville's quarterback against the Lions. It also appears that Leftwich suffered damage to more than one ligament in the knee, and his playing status for the rest of the season still could be in jeopardy if Monday's examination reveals a more extensive injury.

Meanwhile, starting linebacker Darryl Smith has a partially torn ligament in his left knee and could miss the game against Detroit. However, running back Fred Taylor, who missed the second half of last week's game against the Texans with a hip pointer, should be ready to play.

* PATRIOTS: New England will be without both of its starting cornerbacks Sunday at St. Louis. Ty Law will be sidelined for at least a month by a broken bone in his foot, and Tyrone Poole remains shelved by a knee injury.

Poole revealed this week that he recently underwent knee surgery but indicated that he is getting close to returning to the lineup. New England's starters against the Rams will be Asante Samuel and either undrafted rookie Randall Gay or Eugene Wilson, who would be moved from safety. If the Patriots move Wilson from safety to cornerback, they would have to play rookie Dexter Reid at safety.

* PANTHERS: Running back Stephen Davis practiced for the second consecutive day, leaving Carolina hopeful he can play this weekend. Davis, who has missed five of Carolina's seven games with a knee injury, had arthroscopic surgery to repair cartilage damage after Carolina's season-opening loss to Green Bay.

He missed the next three games, but tried to come back against Philadelphia in Week 5. He rushed for 66 yards on 15 carries, but developed swelling after the game that forced him to sit out the last two weeks.

* VIKINGS: Minnesota linebacker Raonall Smith will miss Monday's game at Indianapolis because of lingering effects from a concussion. Smith, who has started three of the Vikings' last four games in place of the injured Chris Claiborne, was hurt on the opening kickoff of last week's loss to the New York Giants. He had a mild concussion Oct. 24 against Tennessee.

Rookie Dontarrious Thomas, who has split time between middle and outside linebacker this season, will start Monday night. Claiborne will miss at least another week with a strained calf.
