Chris Mack was in quite the celebratory mood after his team defeated John Calipari's Kentucky Wildcats on Dec. 26, but the Louisville Cardinals men's basketball head coach apologized for his actions after video of him enjoying the win went public.

As Shannon Russell of the Louisville Courier Journal noted, video of Mack and former Louisville and Buffalo Bills football player Eric Wood celebrating the win went viral when Wood said Kentucky's success against the Cardinals was over now that former associate head coach Kenny Payne had moved to the New York Knicks staff.

Mack said the video was a "joke" and revealed he called Calipari to apologize, per 247Sports. 

The Louisville coach also said his counterpart was "gracious as always" and offered some advice.
