Athletic director Jack Graham also ordered Lupfer to undergo anger management and diversity training at his own expense.
Lupfer issued a statement saying he was grateful to keep his job on Jim McElwain's staff and said "I am deeply sorry for my behavior, which does not represent who I am or my values."
Lupfer got into a verbal altercation with the Cougars' QB after his first TD throw. His slur was caught on ESPN cameras and marred the Rams' comeback from a 22-point deficit for a last-second 48-45 win to kick off the bowl season.
