Update: This is now official.

Berkstresser suffered knee injury in practice Oct. 15, later reported discomfort to training staff. MRI Monday, surgery yesterday — Dave Matter (@Dave_Matter) October 25, 2013

Missouri sophomore quarterback Corbin Berkstresser will miss the Tigers' Saturday night matchup against South Carolina with a leg injury. That leaves the Tigers very thin at the position with only freshman available, according to multiple reports.

Multiple sources say Mizzou backup QB Corbin Berkstresser will sit out Saturday due to a leg injury. QBs down to Mauk & true FR Eddie Printz — Ashley Zavala (@ZavalaA) October 25, 2013

Berkstresser was the backup for freshman Maty Mauk, who is starting in place of injured senior James Franklin. Mauk's backup will now be true freshman Eddie Printz, a former three-star prospect from Georgia who choose the Tigers over offers from Florida State and UCLA, among others.

Berkstresser made one apearance this year, throwing an incompletion on his only pass attempt. As a freshman in 2012, he completed around 50 percent of his throws for six yards per attempt to go with five touchdowns against seven interceptions.

In his first career start, Mauk completed 18 of 36 passes for 295 yards with a touchdown and an interception against the Florida Gators.
