The Seattle Seahawks could be without their best defensive lineman for Sunday's bout with the Philadelphia Eagles. Defensive end Jadeveon Clowney is questionable to play on Sunday, as he did not practice all week with hip and foot injuries.

On Friday, Clowney skipped practice altogether to receive off-campus treatment for his hip injury, according to head coach Pete Carroll. His status for Sunday remains unknown.

He's questionable at this point with a sore hip. He had a little off-campus treatment. We'll see how he is on game day,” Carroll said on Friday, via Curtis Crabtree of Sports Radio KJR.

Carroll noted that Clowney felt the injury coming out of their Week 10 win over the San Francisco 49ers. Luckily, he had a bye week to recover, which, according to him, came at just the right time.

“It was perfect timing,” Clowney said of the bye on Wednesday, per Crabtree. “I think we were all a little banged up going into the last game. Everybody was looking forward to the bye. Came at a perfect time. Now, we’ve just got to come back and pick up where we left off. Continue to try to keep the ball rolling.”

The last time Clowney hit the field, he dominated en route to a Seahawks upset win over the 49ers. In the Monday night clash, he had his best game as a Seahawk, recording a sack, five quarterback hits, a forced fumble and a fumble recovery for a touchdown.

If out, Clowney will be missed on Sunday.
