Minnesota Vikings quarterback Teddy Bridgewater suffered what a serious leg injury Tuesday during practice.
An ambulance pulled into the facility shortly after the third-year quarterback went down during a non-contact drill.
Bridgewater apparently was in the pocket during a drill before collapsing to the ground, clutching his left knee.
Head coach Mike Zimmer said during a press conference later Tuesday that Bridgewater suffered a “significant knee injury.” Zimmer didn’t put a timetable on Bridgewater’s return, but it could potentially end his season.
The rest of the Vikings practice was canceled.
Bridgewater was having a solid preseason coming off the heels of his first Pro Bowl berth last year. He threw for 3,231 yards with 14 touchdowns, while completing 65.3 percent of his passes.
The Vikings backup is veteran Shaun Hill and Joel Stave is also on the roster.
