Vikings' Bridgewater suffers apparent serious knee injury

Minnesota Vikings quarterback Teddy Bridgewater appeared to injure his left knee on a non-contact play during team drills Tuesday, according to multiple reports.

Players were seen praying following Bridgewater's injury, and the Vikings canceled the rest of practice.

An ambulance arrived on the scene shortly after he went down, then left. It's unclear if Bridgewater was on board. If he was, it suggests his injury is more severe than a ligament tear.

A first-round pick in 2014, Bridgewater led the Vikings to the playoffs in 2015 and was expected by many to take a big leap in his third year in offensive coordinator Norv Turner's scheme.

Veteran Shaun Hill and undrafted rookie Joel Stave follow Bridgewater on the Vikings' quarterback depth chart.
