I assume hes been cleared from any type of swelling and bleeding that would typically be of concern with an injury like that. Its fine for him to travel back if thats the case. Though if I was the team I would've made him stay. They are in even deeper deep shit now and any negative PR is adding on it. Allowing Tua to even play this game is absurd. He was concussed Sunday, no question about it. Now hes had two serious brain injuries in the past week.
