He was set to make the first defense of his title against Mike Gavronski on December 26 at the Shine Exposition Hall in Los Angeles. After Morrell failed to weigh within the super middleweight limit, reports claimed that he had been stripped of his title. However, it was later revealed that a clause in the fight contract allowed for the fight to continue as a non-title contest. Morrell defeated Gavronski via third-round KO.

The following month, Morrell was elevated from interim champion to Regular champion. The first defense of his Regular title came against Mario Cazares on June 27, 2021, at the Minneapolis Armory. Morrell Retained his title via first-round KO.

While Benavidez controlled most of the fight, Morrell scored a flash knockdown over Benavidez towards the end of the 11th, the second of Benavidez's career. However, following a furious exchange at the end of the round, Morrell threw a shot after the bell that connected on Benavidez, which prompted Thomas Taylor to deduct a point from Morrell. After a similarly high-paced 12th round, Morrell lost via a unanimous decision, losing by scores of 118–108 and 115–111 twice, with Benavidez taking his WBA title in the process.
