Two Redskins hurt during collision in pregame warmups, declared inactive (VIDEO)

It's pretty rare to see two teammates knock each other out of a game by colliding into each other.

That's almost impossible in pregame warmups, which is why the Washington Redskins have to be shaking their heads.

Before Sunday's game against Tampa Bay, the Washington Post reported that receiver Aldrick Robinson and safety Brandon Meriweather collided in pregame warmups and were both injured. The Redskins had to declare both inactive in one of the weirder injuries in the NFL in some time.

Robinson was in the end zone with his head down, and never saw Meriweather, who looked like he was running to catch a pass. The two had a brutal collision, with Robinson being hit in the head and Meriweather going down grabbing his knee. Robinson stayed on the turf for a while, the Post reported, and was checked out by both teams' training staffs. The injury was particularly cruel for Meriweather, who hasn't played in a game yet this season because of knee troubles. He limped off the field and was ruled out.

As far as unusual and rare NFL injuries go, it'll be tough to top what happened to the Redskins' duo.
