Teddy Bridgewater, who suffered a gruesome knee injury last August, is already back to practicing with the Vikings

On Tuesday, the Vikings' Twitter account posted a short video from OTAs that showed Bridgewater doing what quarterbacks are required to do: taking a snap from under center, dropping back to pass and throwing the football.

Take a look:

Bridgewater's injury -- a torn ACL and dislocated left knee -- was so severe that an ambulance had to immediately escort him to the hospital. It was reported that there was concern among doctors that the injury could end Bridgewater's career. The Vikings' move to trade for Sam Bradford signaled that they weren't really counting on Bridgewater returning anytime soon. They didn't pick up his fifth-year option, which is guaranteed for injury.

But Bridgewater worked his way back to the field, though it's still unclear when he'll be completely healthy. There's a difference between throwing passes in practice and throwing passes in the vicinity of pass-rushers. Regardless of when that happens, Tuesday's video serves as a feel-great moment for a player who was on the cusp of cementing himself as the Vikings' franchise quarterback before suffering that gruesome, fluky injury.

"He's had a great attitude through the whole process," Vikings tight end Kyle Rudolph told ESPN.com over the weekend. "In my time in sports, it's probably been one of the craziest injuries I've ever seen, just the way it happened, the severity of the injury and the recovery he's had to go through. No one has had a better attitude than he has."
