UNDATED (AP) — Veteran quarterback Shaun Hill and rookie Joel Stave have just become very important members of the Minnesota Vikings.

Starting quarterback Teddy Bridgewater is expected to miss at least the upcoming season while recovering from a dislocated left knee and torn ACL suffered in a freak practice injury on Tuesday. The non-contact injury occurred when he tried to plant his left foot to throw a pass. The knee was placed in an air cast before he was taken to a nearby hospital.

The 36-year-old Hill has started just 34 games during his NFL career, eight since the end of the 2010 season. Stave just completed a four-year college career with Wisconsin, where he completed 59.5 percent of his passes for 7,635 yards, 48 touchdowns and 37 interceptions. Stave was signed as an undrafted free agent.

Here is the statement from Vikings Director of Sports Medicine and Head Athletic Trainer Eric Sugarman on Teddy Bridgewater:

Teddy Bridgewater suffered a non-contact injury today at practice. The injury was quickly identified as a dislocated knee. The injury was stabilized, and he was transported to a nearby hospital for treatment and evaluation. After undergoing an MRI, it was determined that Teddy suffered a complete tear to his ACL and other structural damage. Fortunately, there appears to be no nerve or arterial damage. Surgical repair will be scheduled within the next few days. Although the recovery time will be significant, we expect Teddy to make a full recovery.
