He was injured at 5:52 in the first quarter of the game that he only played 6 minutes in.
I have had players injured, and then after the game they were OK. I even had a player injured in two games in a row and then play the 3rd game in the week.
But your player may have been injured, and you didn't see it for the 2nd game. Or there might be some problem showing injuries. There was another team that has reported a similar situation.
