San Francisco 49ers stud quarterback Jimmy Garoppolo was in the midst of leading a potential comeback against the Kansas City Chiefs when he stepped out awkwardly and was leveled by a defender. Garoppolo never got up, clenching his knee almost immediately. 

The injury doesn't look promising on the replay, and you never want to assume or say it, but this looks like the same reaction we see whenever someone tears an ACL. The 49er fans weren't given any encouragement by watching Garoppolo go from the medical tent to being carted off the field pretty quickly. 

All the 49er fans and fantasy owners can do is pray and wait. You can pretty much call it a season for the Niners if this injury turns out to be serious.
