Misha Cirkunov battled Alex Nicholson Saturday night in a brutal battle that resulted in Nicholson's jaw being cracked.
Nicholson has a fractured jaw and most likely needs surgery, per the UFC.

Per Uproxx, Cirkunov's challenger came into the matchup having suffered a broken jaw in August, and things might have gotten significantly worse after Nicholson's bout.
Maybe the only silver lining — he's now engaged after proposing during weigh-ins.
