There is a fan that does a podcast. TD Phins Talk
In this video he proves that he was not feeling the effects of a concussion during the game based on game play. Their fanbase does NOT think he is faking it, BUT they do believe he did not feel the effects till after the game. Also note. IT was not just after the game he told his coaches something was wrong with his head. it was later that night.
All this being said, I think Tua is a good dude and I think 3 in 3 months... he should retire.
The part they missing is... Tua went to the teams Doctors... not the other way around.
