James Franklin's status was upgraded to questionable as his separated throwing shoulder continues to heal, but Maty Mauk will likely make his third career start as Missouri faces Tennessee on Saturday.
The Tigers (No. 9 BCS, No. 10 AP) are still trying to recover from last weekend's 27-24 double-overtime loss to South Carolina, as Andrew Baggett missed a 24-yard field goal attempt off the left post.
"The sun came up again Sunday morning," nose guard Lucas Vincent said.
Missouri (7-1, 3-1) retains a one-game lead over South Carolina in the SEC East heading into Saturday night's visit from Tennessee (4-4, 1-3), but the Gamecocks own the head-to-head tiebreaker.
If South Carolina wins its remaining two conference games at home against Mississippi State and Florida, Missouri would have to win its last four to reach the conference championship game in Atlanta on Dec. 7.
"If you're a player here, why would you not be encouraged?" coach Gary Pinkel asked. "You should be the most fired-up football player in America with the opportunity and options that we have in front of us. But we've got to take care of our business."
For his part, first-year Volunteers coach Butch Jones doesn't think the Tigers will dwell on their loss for long.
"Every game is like a new chapter in a book," he said. "It has different story lines, the way the game goes, the flavor of the game. What you did last week has no bearing on the outcome of this week."
