Cowboys tight end Jason Witten will be a game-time decision Thursday because of a sprained foot. He suffered the injury in the second quarter Sunday against Washington, but was able to finish out the game.
Witten did not practice Monday and was limited Tuesday for the team's no-pads workout.
"Jason did go through some of the walk-through as he did yesterday," Phillips said. "We're a little bit worried about him being able to play."
The Cowboys have committed to using a two tight-end formation with Witten and Martellus Bennett. Rookie tight end John Phillips has also seen considerable action as a blocker. Phillips said if Witten can't play, it shouldn't affect their ability to utilize the formation.
Of course, John Phillips isn't Witten, who leads the team with 54 receptions. He's also quarterback Tony Romo's security blanket. The Cowboys just want to make sure they're cautious. Witten played with a broken rib last season and hasn't missed a game since 2003.
"It's a situation where if it's not well enough he could hurt it more," Phillips said. "That's a concern."
