LSU quarterback Myles Brennan has decided to end his college football career after five seasons with the Tigers.

– LSU coach Ed Orgeron says his team is contending with a corona virus outbreak and resulting quarantines that have made it difficult to know whether a number of starters or regulars will be available for Saturday's scheduled game against No. “We're talking to the doctors right now to see what's the best for Myles,” Orgeron said during his usual Monday-of-game-week media conference. The number of related quarantines due to possible exposure also have thinned his roster in recent days, he said. The SEC requires teams to have at least 53 scholarship players available, less than that and the scheduled game cannot be played. By the middle of the week, LSU expects to know if the game could still be held this weekend as scheduled, Orgeron said.

The Tigers had been ranked in 43 straight polls, dating to Nov. 5, 2017. Following Cam Newton's departure the Tigers spent much of the '11 season outside the Top 25, finishing 8-5 and unranked.
