Missouri head football coach Gary Pinkel said on Monday that quarterback Maty Mauk has been suspended indefinitely and freshman Drew Lock will remain the Tigers starting quarterback.

Pinkel wouldn’t elaborate on the reason for the suspension.

Mauk started the first four games this season and has completed 51.8 percent of his passes for 654 yards, six touchdowns and four interceptions. His 145 yards on the ground are second-best on the team.

Mauk and offensive lineman Malik Cuellar were suspended before the team’s game against South Carolina last week.

Lock, a true freshman from Lee’s Summit High School, make his first career start last Saturday against South Carolina and he completed 21-of-28 passes for 136 yards and two touchdowns as the Tigers won 24–10.

Lock and the Tigers host No. 11 Florida this Saturday at 6:30 p.m.  The game will be broadcast on ESPN 1550 AM.
