FRISCO, Texas – Head coach Jason Garrett confirmed Monday that right guard Zack Martin is once again dealing with a sprained MCL in his left knee.
Martin sprained his knee Oct. 21 at Washington and missed a few plays due to the same injury Nov. 11 at Philadelphia. He limped off the field in the second half of Sunday's 29-23 overtime victory over the Eagles and was unable to return to the game.
"It's the same knee and it's really the same injury," Garrett said. "It's an MCL. So we'll just take it day by day. He's as tough as they come. Whatever he can do to play as quickly as he can, he's going to do.
"I visited with him last night. Our medical people saw him again today. He's obviously getting rehab and treatment on it. We'll see how it responds."
It's uncertain if Martin will be able to participate when the Cowboys return to practice Wednesday. He has not missed a start this season, and last week he was a full participant in practice for the first time in nearly a month.
If Martin can play this Sunday against the Colts, it would be a homecoming of sorts for the Indianapolis native who starred at Notre Dame before getting drafted 16th overall by Dallas in 2014.
Garrett praised rookie Connor Williams for stepping in at right guard Sunday after Martin's injury. Williams, the Cowboys' second-round draft pick, started the first eight games at left guard before undergoing a knee scope in November. Xavier Su'a-Filo has continued to start at left guard since Williams' return.
