During tonight’s game against the Seahawks, San Francisco 49ers wide receiver Mario Manningham suffered a bad-looking knee injury and ended up getting carted to the locker room.
Manningham was helped to the sideline, but now he's being carted from there to the locker room. Still was putting some weight on knee.

I think there’s a good chance Manningham may have torn his ACL. As soon as soon as we get an update, we’ll be sure to let you know.
