Burns retires; Malott to crack top-15; Tsarukyan calls out Covington after RAF win

This post provides several updates from recent MMA events. Gilbert Burns has retired from competition. Ian Malott is expected to enter the top-15 rankings at welterweight, though the author questions his potential against elite competition. The previously scheduled bout between Guskov and Blachowicz has been cancelled, with Polish fighter Ibo Baraniewicz stepping in as a replacement. Armenian fighter Arman Tsarukyan defeated Uriah Faber 13-1 at a Real Action Fighting event and immediately called out Colby Covington afterward, promising to dominate him 10-0 and saying people have forgotten about Covington as a fighter. Khamzat Chimaev has also signed with RAF, and Bo Nickal responded by challenging the champion.
