I'm not even sure why Tua was allowed to play in the second half of the Bills game let alone play against the Bengals on only a few days rest or some.
It's pretty clear that he had a concussion in the Bills game and everyone watching knew he should not have been out there against the Bengals.
I know he wants to be tough and be there for his team but he's risking his health and career by being out there.
All the best to Tua, we hope to eventually see him back out there!
