The circumstances behind his suspension were a bit ridiculous, since Browner was suspended for not complying with the NFL's testing policies when he wasn't even an NFL player.
The details, via ESPN:
So the NFL expected to drug test a guy who was working outside the NFL, and they suspended him for not submitting to their testing when he wasn't an NFL player?
It was one of the more ridiculous policies the NFL has had, and Browner and his attorneys used that fact in the appeal.
Now, Browner is finally being reinstated by the team, just in time for him to be an unrestricted free agent. He's now able to sign with any team he wants, and there's likely to be some interest in him, since he's a quality cornerback with great size.
We'll see which team decides to take a chance on him.
