According to ESPN's Andrew Brandt, former Bengals tight end Ben Utecht has won a grievance against the team over his release stemming from concussions in 2009. While Utecht's multiple concussions were bad enough for the tight end to admit that there are parts of his life he no longer remembers, he claimed the Bengals didn't sufficiently test him before releasing him. Since he won his grievance, we can assume that someone agreed with him.

Utecht didn't play another snap in the NFL after he was released from the Bengals and he has gone on to have a decently successful recording career. He has released several albums and seems to be happy with his post-football career.
"In 2009 my NFL career was promising, but it ended suddenly with a brain injury. Three years later my family and I have closure with the successful conclusion of my contract dispute. We are grateful for the support we have received from all of our friends in professional football and beyond. I will continue to help the NFL in any way I can to educate people about brain safety and the seriousness of this issue."
