He will be gimpy. Ligaments and tendons don’t like to bend like that with weight on top. He’s ok longterm could mean a sprain which is ligament damage.
If it were ssmiff taking that tackle, he'd be rolling around on the sidelines like lt dan with a double amputation. But Tillman looks okay.
I think we’ve seen enough that Akron is a bad risk for any future games even if the played us for free.
