And it sounds like taking a stand on concussions has just ended an NFL career...

Jeremy Shockey has pretty much just ended his NFL career with a Twitter rant.

According to USA Today, Shockey made the following Tweets in response to the NFL's commitment (or, Shockey believes, lack of!) against concussions:

• "The no it all Rog goodell lied to every player and told us concussions will not effect us in life that a LIE!"
•  "It would be great to give the health study on NFL players on a commercial during the games!! just want the fans and congress to know! FACT"
•  "Science tells me I'll be dead time in 54yrs old!! What would u do?"

 Is he near the next to go?
