Late in the fourth quarter, first-round pick defensive end Mykel Williams went down with a right knee injury. Afterwards, coach Kyle Shanahan told reporters that they fear Williams injured his ACL. A torn ACL would sideline Williams for the remainder of the season.

The inconsistency of NFL fields was brought to the fore again Sunday when San Francisco 49ers top pick Mykel Williams injured his right knee late in the game.

As feared, Mykel Williams indeed suffered a torn ACL in the Week 9 win over the Giants, meaning the 49ers will lose yet another player for the rest of the season.
