Williams optimistic after surgery

ORCHARD PARK, N.Y. (WIVB) - Mario Williams is on the mend, after bye week surgery on his injured wrist. Despite missing practice Monday, he says he will play Sunday at Houston.

The Bills' defensive end has been bothered by the wrist for two months. He admitted, it bothered him both physically and mentally, which ultimately led him to go under the knife.

"I just had it cleaned out," said Williams. "From whenever it got injured early on in the year, there was a bunch of junk and stuff that was in there. That is the reason why I could not have motion and could not really use it"

Williams said today, his range of motion has already improved.

"This is not me. I have said that before. I have never had something where it has lingered this long," said Williams. "It either is season-ending or it (gets better) in a week. Like I said, it has been almost nine weeks now. That has just been tough. But you get injured. Everybody gets injured and things like that—setbacks. I think the biggest thing for me is just being able to rebound for the second part of the season and get after it."

As a precautionary measure, Williams will wear a cast on his wrist this Sunday against the Texans. The Bills expect him to return to practice Wednesday.
