Two of MMA’s handful of well-known heavyweights who don’t call the UFC home both saw action on the same card over the weekend with each earning a victory in their respective rumbles.

Headlining M-1 Challenge 31, Aleksander Emelianenko wowed his fellow Russians with a second round knockout of Tadas Rimkevicius, snapping a three-fight winning streak for “The Lithuanian Bear” and running his own record to 19-5 in the process. The performance marked Emelianenko’s second consecutive finish of an opponent and tenth in his last twelve fights (the two exceptions being losses).

Also highlighting the card, former UFC contender Jeff Monson (44-13) narrowly outpointed submission specialist Alexey Oleinik (33-9). Olenick, who owes 27 of 33 total wins to tap-outs, almost came away with the biggest triumph of his career in beating Monson but ultimately lost a Split Decision. The fight was the first for Monson, also apt on the ground, since losing to Fedor Emelianenko in November.

Though nothing has been mentioned their performances could set up a potential “super-fight” between the two under the promotion’s banner.

Bruno Carvalho also added a notch to his win column at the event, beating formerly undefeated Ramazan Esenbaev by way of Unanimous Decision.
