While most eyes seem to be on the welterweight featured bout between Gilbert Burns and Khamzat Chimaev at UFC 273, Aljamain Sterling and Petr Yan made quite the case for themselves during Wednesday's media day in terms of generating interest. On this edition of Heck of a Morning, MMA Fighting's Mike Heck takes calls surrounding that rivalry bout to unify the bantamweight title, Gilbert Burns vs. Khamzat Chimaev, other sleeper fights on the card — which includes Vinc Pichel vs. Mark Madsen getting bumped to the main card — and much more. You can listen live to Heck of a Morning Tuesdays, Thursdays, and Fridays at 8 a.m. ET on the MMA Fighting Twitter Spaces.
