This is a different injury than the hamstring issue which kept him out of two games already this season. That injury was his left injury, the more recent injury is his right leg.
"It's really early," Austin told ESPN after the game. "I need to get an MRI and wake up in the morning and see how I feel. I can't say I'll be back and practicing on Thursday or playing. It's very surprising. You don't expect something like that but the other guys stepped up as they should and I'm going to try to get back. It's paramount I try to get back as quick as I can."
