Dallas Cowboys linebacker Sean Lee is scheduled to have surgery Thursday to repair the anterior cruciate ligament in his left knee, coach Jason Garrett said after practice Tuesday.
Lee suffered the potentially season-ending injury on May 27, the first day of organized team activities.
He has done some light rehab the past couple of weeks to strengthen the knee while also going over his options.
Garrett said the Cowboys will wait until after the surgery to determine Lee’s status for the season. They could put him on injured reserve or place him on the physically unable to perform list, which would allow him to rehab and possibly return in late November or early December.
Never miss a local story.
The recovery time from a torn ACL is typically six to eight months.
This is not Lee’s first experience with a major knee surgery. Lee tore his right ACL in April 2008 while at Penn State, then partially tore his left ACL during the 2009 season.
Veteran Justin Durant is working with the first team with rookie fourth-round pick Anthony Hitchens backing him up. DeVonte Holloman, who has been held out of OTAs and minicamp because of injury, will also get a look in training camp.
Martin at center
The Cowboys gave Zack Martin a look at center during practice Tuesday and plan to keep doing it.
“We viewed him as a guy who could potentially play five offensive line spots when we drafted him,” Garrett said. “He’s certainly done a very good job at guard. We’ll try to give him some snaps at center as well.”
Martin comes to the Cowboys with 52 games of big-time college experience at left tackle. He never played a game at guard in college, and he only snapped during workouts for NFL teams in the off-season.
“He’s a really, really smart football player,” Garrett said. “The game comes very easily to him from a mental standpoint.”
Patience with Johnson
The Cowboys held safety Matt Johnson out of Tuesday’s practice, but he appears close to being ready to work again, and the team remains willing to wait.
“We feel like what he’s done up to this point is worthy of us having some patience with him,” Garrett said.
Johnson, drafted in the fourth round in 2012 by Dallas, has been slowed by hamstring injuries so much that he has hardly practiced. He got on the field for the preseason opener last year, but then suffered an ankle injury just a few plays in.
This year, he began the off-season and OTAs healthy, but last week another hamstring injury sidelined him.
Little extra for Romo
The Cowboys aren’t planning to ramp up Tony Romo’s activity very much next week in the mandatory minicamp.
“We’ll take him day by day like we do with all the other guys. But I wouldn’t see it changing it dramatically,” Garrett said Tuesday as the final week of OTAs started.
The Cowboys have a three-day mandatory minicamp starting next Tuesday. Garrett also said the format of the practices would not change much.
Romo has been throwing during the individual drills, but he and the rehabbing players have been held out of the team activities.
• The Cowboys signed former Texas Tech defensive tackle Dartwan Bush, who participated in the rookie minicamp as a tryout player.
• The team released safety Marvin Robinson and cornerback Jocquel Skinner. Both reached injury settlements.
