The Keg of Nails is a traveling trophy in college football, awarded since 1929 to the winner of games between the Universities of Louisville (U of L) and Cincinnati (UC), cities now connected by Interstate 71. The trophy is a replica of a keg used to ship nails. The exchange is believed to have been initiated by fraternity chapters on the UC and U of L campuses, signifying that the winning players in the game were "tough as nails." The rivalry went on hiatus following the 2013 season, as Louisville moved to the Atlantic Coast Conference on July 1, 2014.
