Well, he was blinded and ended up in the hospital. In fact, did he ever make it back all the way?
No, unfortunately, he never really did.
You are thinking of Orlando Brown, and he was playing for the Browns when he was hit in the eye with a penalty flag from Jeff Triplette while playing the Jaguars. He had some very serious eye injuries resulting from it, and he missed three or four season of action. He later came back a few years later and played for the Ravens for, I think, three years before finally retiring. Before the injury, he was actually one of the top tackles in the league, but after the long hiatus he just wasn't the same.
Anyway, he eventually got his due. He filed a lawsuit against the NFL in 2001 for approximately 200 million dollars, and if I remember correctly Johnny Cochran was actually his lawyer. Anyway, the NFL decided to settle out of court with him. I believe he got somewhere in the neighborhood of 25 million dollars when it was all said and done.
