Missouri coach Gary Pinkel said Monday that quarterback James Franklin will miss three to five weeks with a shoulder separation.
Franklin was injured during Saturday's upset win over then-No. 7 Georgia. Missouri moved up to No. 14 in both major polls.
Franklin landed hard on the shoulder after being tackled early in the fourth quarter with Missouri up 28-26. He was replaced by backup Maty Mauk.
Franklin went 18 of 27 for 170 yards and rushed for 23 yards with a touchdown as Missouri jumped out to a 28-10 lead and eventually won 41-26.
Pinkel confirmed that Mauk, a redshirt freshman, would get the start Saturday against No. 22 Florida, with Corbin Berkstresser backing him up.
CBSSports.com reported Sunday that Franklin would be out at least six weeks.
