Mario Williams signed with the Buffalo Bills in the offseason, but his departure from the Houston Texans wasn't his choice.

"Everybody looks at as you just up and leave," Williams said. "But you don't know the fact of basically being told 'We're not giving you anything as far as an offer or anything like that.' So your hands are tied in that aspect. Everybody else looks at it like you just went in free agency and left. Obviously, there was plenty of time for things done that wasn't done.

"That's fine with me. I just wish everybody else who runs their mouth and says this or that knew the whole story about it before making a decision about me just abandoning fans and the team and everything else like that because that's not my role. I'm not that type of guy.

"I'm here, and I'm ecstatic about it. We made the best of it. But there was never an offer from the general manager [Rick Smith]. It was a one-way door that was opened."

Mario Williams is considering undergoing surgery on his injured left wrist.

Williams signed a six-year, $100 million contract in the offseason, but has been a disappointment.

Williams has blamed his wrist for his lack of production.
