Uga IX, the former mascot of the Georgia Bulldogs, died Monday in his sleep, according to the Seiler family, longtime owners of the Georgia line of mascots.

The 11-year-old Russ was officially retired Nov. 21 with the coronation of "Que," Uga X, as Georgia's mascot before the football game against Georgia Southern in Athens.

The half-brother of Uga VII, Russ had served as the mascot on and off since 2009, after working a total of 63 Georgia football games. Uga IX had compiled an overall record of 44-19.

He served as an interim Bulldog mascot for a total of 25 games, working nine games during the 2009 and 2010 seasons after Uga VII and VIII passed away. Russ roamed the sidelines at all 14 games during the 2011 season. He then served for two wins at the beginning of the 2012 season before being officially promoted as Uga IX prior to the Florida Atlantic game in 2012.

Georgia Bulldog mascots have been owned by the Frank W. “Sonny” Seiler family of Savannah, Ga., since 1956.
