It was a weird week for Bryan Stork. He went from released to traded to retired, to unretired and traded to the Redskins. That prompted this tweet, which has since been deleted, from Stork dated August 28: "I will forever have nothing but great memories at the #patriots. Looking forward to making more at #redskins #HTTR."

A day later, the saga continues; according to ESPN.com, Stork failed his physical in Washington, which nullified the trade, which means his (currently unretired) rights revert back to New England.

So how did we get to this point? On August 24, the Patriots informed Stork, 25, that he would be released. Word made it's way to Redskins general manager Scot McCloughan, whose team has needs at center. After not seeing Stork's name on the waiver wire, McCloughan called the Pats and swung a deal.

So Stork went from released to traded -- except that Stork, who has suffered at least four concussions during his career, contemplated retirement before the trade was completed. Apparently, he had a change of heart (hence the since-deleted tweet mentioned above), though now that Stork has failed his physical and his rights revert back to New England, perhaps retirement remains an option (since it's fair to assume that the Pats still want to release him).

If Stork does retire, and it's related to concussions, he would be the latest in a long line of young NFL players to give up the game because of concerns over the long-term effects of head trauma.
