UMass will retire Calipari's jersey prior to a game on December 16.
Here are details from Masslive.com:
With the official unveiling of the University of Massachusetts basketball team's complete 2015-16 schedule Thursday, we now know the date of a game UMass fans have been looking forward to since March – John Calipari's jersey retirement ceremony.
Calipari will have his jersey lifted to the Mullins Center rafters on Dec. 16 prior to the Minutemen's non-conference matchup against New Orleans. An exact start time for the game has yet to be set, but the ceremony will likely take place in that 15-20 minute window right before tipoff.
Memphis announced last night on social media that the school will be honoring Calipari December 28-29.
Will be honoring Hall of Fame coach @UKCoachCalipari in Memphis, Dec 28-29. Stay tuned for details. Will be a great homecoming.— Dr. M. David Rudd (@UofMemphisPres) September 9, 2015
Calipari released a statement last night about being honored by both schools:
“I appreciate UMass and Memphis for deciding to honor what we were able to accomplish. UMass gave me my first opportunity and Memphis revived my career. I have a special place in my heart for both Amherst and Memphis. Ellen and I have made so many friends and created relationships with so many people at both schools that we will forever cherish. This week is about all of the schools, all of the staffs, all of our friends, all of our supporters, but most importantly, all of our players from all three schools.”
