I'll give you THREE things that are GREAT about this game:
1) Allen did not break either of his arms
2) Allen did not blow out either knee
3) Allen did not break either leg.
He turned to a teammate and said "Nah I'm fine" as he walked past.
For what that's worth. I'm sure he wouldn't be the first guy to say that while actually being concussed, but I think he's OK.
