Former UFC interim welterweight champion Colby Covington has officially notified the promotion of his retirement, ending a decade-long run in the organization. The 38-year-old fighter, known for his aggressive wrestling and polarizing persona, leaves the UFC with a 12-5 record in the octagon, including dominant wins over Jorge Masvidal, Tyron Woodley, and former champion Robbie Lawler. His final fight came in December 2024, when Joaquin Buckley stopped him in the third round.

Covington’s retirement comes as a surprise, especially as he had publicly campaigned for a spot on the UFC’s June 14 card. However, he remains active in grappling, with a scheduled match against Chris Weidman on May 30 under the RAF banner. This suggests a shift in focus rather than a full exit from combat sports.

Alongside Covington, the UFC roster updates confirm the departures of Mayra Bueno Silva and Brad Riddell. Bueno Silva departs after six straight losses, including a title fight defeat to Raquel Pennington. Riddell, once a rising lightweight, exits on a three-fight skid, last withdrawing from a bout in 2024. The roster moves signal a changing of the guard in multiple divisions.
