Jason Witten suffers sprained MCL

IRVING, Texas -- The bye week comes at a perfect time for Dallas Cowboys starting tight end Jason Witten and left guard Kyle Kosier, who both suffered right knee injuries Sunday against the Houston Texans.

Witten suffered a sprained MCL in his right knee in the Cowboys' 27-13 victory. The six-time Pro Bowler, who caught seven passes in the game, said he was fine, but his practice status for this week is uncertain.

Kosier left the game with 11:41 to play in the fourth quarter after he tweaked the MCL in his right knee. He did not return. Kosier missed the season opener after injuring his MCL in training camp.

Kosier said the bye week will help in his recovery, and he doesn't think he'll miss any games. However, his practice time could be limited during the bye week.

Cowboys coach Wade Phillips said he was a little concerned about Kosier's status for the Week 5 game vs. Tennessee.

"I think it's more iffy on Kosier," Phillips said. "I don't think there's much doubt that Witten will be able to play. He may not be able to [practice] this week. I think Kosier is right in that two-week span. Now that's preliminary. That's not a doctor report."
