The shot came from Bengals safety George Iloka, who appeared to go high on Finley. No penalty was assessed on the play, but the league will certainly be reviewing the hit for a possible fine.
Finley initally hopped up quickly after the hit and began jogging off the field. He didn't make it far before he started feeling it, stumbling to a knee and rolling onto his side.
No official word has been released yet, but it certainly appears as though Finley may have suffered a concussion on the hit. His availability for the remainder of the game is unknown, and he'll have to pass concussion tests before returning.

And shortly thereafter, confirmation came down that Finley did suffer a concussion and was done for the day.
