Ronda Rousey's best friend was finished by TKO in just 37 seconds by debuting Amber Leibrock at Invicta FC 13 on Thursday night in Las Vegas.
Leibrock (1-0) dropped Shafir (1-2) with a punch then landed ground and pound until Shafir was out cold. Shafir was going for a leglock, but Leibrock seemed to hold onto the cage to keep herself upright. Referee Steve Mazzagatti didn't see it.
Shafir has now lost two in a row by first-round knockout after going undefeated as an amateur. Watch the knockout below.
WOW!
