Patriots' Alan Branch has 4-game suspension rescinded, so what happened exactly? (Shutdown Corner)

It’s an unusual event when a player has an NFL-imposed suspension rescinded before his appeal hearing even occurs, but that’s apparently what happened to the New England Patriots’ Alan Branch. Branch had filed for an appeal, but before that even occurred the NFL reviewed the case and cleared him of any wrongdoing. This is a very rare thing in the NFL.
