Missouri will be without its starting quarterback Maty Mauk and junior offensive lineman Malik Cuellar Saturday against South Carolina for “disciplinary reasons related to violation of team policies.”

Mauk hasn’t had the greatest start to the 2015 season, throwing for 654 yards, six touchdowns and four INTs through four games. He’s completed just 51.8 percent of his passes.

Talented freshman quarterback Drew Lock is expected to make the first start of his Mizzou career Saturday against the Gamecocks.
