This time last year, Mike McCray was preparing as a captain for his final season at Michigan.

12 months later, he's choosing to walk away from the game.

The Dolphins rookie, signed as an undrafted free agent, posted a message on Twitter on Tuesday.

"For some time now, I have been playing the game of football for the wrong reason and during this time I sacrificed my happiness and my well being," McCray wrote.
