Fight Analysis & Prediction
No. 2 Arman Tsarukyan vs. No. 10 Mauricio Ruffy Co-Main Event Betting Odds
| Fighter | Moneyline | Spread | Rounds | Win by Decision | Win by KO/TKO/DQ | Win by Submission | Go the Distance |
| Arman Tsarukyan | -330 | -5.5 (-200) | O2.5 (-115) | +350 | +195 | +220 | Yes (+240) |
| Mauricio Ruffy | +265 | +5.5 (+155) | U2.5 (-115) | +1,100 | +400 | +2,800 | No (-330) |
Arman Tsarukyan hasn’t fought in the UFC since last November, but he’s been keeping busy with RAF grappling matches in the meantime. Tsarukyan is 10-2 in the UFC, and his only losses came in his promotional debut against Islam Makhachev and a questionable against Mateusz Gamrot in 2022.
Mauricio Ruffy is the next guy on Tsarukyan’s hit list, which already includes wins over division mainstays Beneil Dariush, Dan Hooker, and Charles Oliveira. Ruffy, meanwhile, has beaten a 40-year-old Michael Chandler and No. 12 lightweight Rafael Fiziev since getting his face cranked by Benoit Saint-Denis last September.
And that loss is one that sticks in our mind when we look at his matchup here with Tsarukyan. BSD is an excellent wrestler and submission artist, but those are also Tsarukyan’s strong points. BSD might be a more dangerous threat when it comes to submitting opponents, but the Armenian is arguably the better wrestler.
When Ruffy starts launching those kicks he loves, Tsarukyan’s going to be ready with the takedown. And we think he’s going to keep the Brazilian there for a large portion of the fight, eventually frustrating him so much that he falls into a Tsarukyan submission.
Best Bet: Arman Tsarukyan to Win via Submission (+220)
