Mike Jenkins may miss 3-4 weeks

IRVING, Texas -- Less than 24 hours after expressing hope that he would be able to play Sunday against Seattle, Dallas Cowboys cornerback Mike Jenkins said he could miss three to four weeks with a hamstring injury.

Without Jenkins, who will have an MRI, Orlando Scandrick would start. Scandrick started in place of Terence Newman in the season opener. Jenkins had been slowed by stinger and shoulder injuries earlier in the season but had not missed a game.

Jenkins suffered the injury early in the third quarter of Sunday's loss at Philadelphia but remained in the game until the fourth quarter. He said Monday the leg felt "about the same," as it did after the game. Jenkins missed two games as a rookie with a hamstring injury.

Meanwhile, Cowboys linebacker Sean Lee will attempt to play with a dislocated left wrist, but he was not sure he would be able to play Sunday against Seattle.

Lee visited with Dr. Bo Frederick, a hand and wrist specialist, Monday in Dallas to determine the extent of the injury. If Lee can play, he would wear a cast, although surgery remains a possibility.

"I don't know for sure what the plan is this week," Lee said, "but I'm definitely going to try to work with the doctors, see how it heals and go from there."

According to a league source familiar with such injuries, if surgery is required Lee could miss the rest of the season. Depending on what would need to be repaired, a player would need up to three months to recover. The Cowboys regular-season finale is Jan. 1 at the New York Giants.

"Right now that's a good deal," Lee said of not needing surgery, "and so hopefully it'll stay that way."

Lee, the Cowboys' leading tackler, suffered the injury on the final play of the first quarter when his wrist was bent backward while attempting to tackle Philadelphia quarterback Michael Vick.

Without Lee, the Cowboys would have veterans Keith Brooking and Bradie James as the starting inside linebackers with rookie Bruce Carter, who only began practicing two weeks ago after rehabbing a torn anterior cruciate ligament, as the backup. The Cowboys also have inside linebacker Orie Lemon on the practice squad.

"I think the biggest thing is to get Bruce more involved on defense," Cowboys coach Jason Garrett said. "He contributed on special teams and had a little package on defense that we wanted to use him on last night. He's the natural one to get more snaps. We have Bradie and Brook in there, who we feel good about, but if Sean is not able to go I think Bruce Carter is the natural one to take more snaps."

Carter played in a special teams role against the Eagles, but his learning curve would have to be sped up.

"I can't wait to get out there and show everybody what I can do," Carter said.
