Burns retires; Guskov-Blachowicz off, replaced by Baraniewicz; Chimaev signs RAF

Gilbert Burns has officially retired from MMA competition. The scheduled fight between Guskov and Blachowicz has been cancelled, but another Polish fighter, Ibo Baraniewicz, will step in as a replacement. Arman Tsarukyan defeated Faber 13-1 and called out Colby Covington post-fight, promising to dominate him and make everyone forget about him as a wrestler. Hamzat Chimaev has signed a contract with the RAF wrestling league. Bo Nickal immediately responded to Chimaev's signing by challenging the champion.
