Missouri suspended junior quarterback Maty Mauk for the rest of the season for disciplinary reasons, just six days after reinstating him.
The Tigers (4-4) play 24th-ranked Mississippi State (6-2) on Thursday night at home.
Freshman Drew Lock has made four starts since Mauk was first suspended.
The school said in a news release Sunday that it will not discuss further details of Mauk's suspension. The first suspension was for a violation of program policies.
