Armenian lightweight fighter Arman Tsarukyan will face Brazil's Mauricio Ruffy in the co-main event of UFC 331, set to take place on September 20 in Los Angeles. Bookmakers have already released the betting odds for the upcoming bout, according to which the Armenian athlete is considered the clear favorite. The probability of his victory is set at odds of 1.25, while odds of 4.00 have been set for his opponent's success.
In the American odds system, Tsarukyan's line stands at -400, meaning a $400 bet is required to net a $100 profit. In Ruffy's case, the odds are +300, where a winning $100 wager yields a profit of $300.
Arman Tsarukyan currently holds a 5-fight winning streak, though this will mark his first appearance in 2026. He last fought in November of last year, defeating Dan Hooker via submission in the second round.
For Mauricio Ruffy, this will be his third bout of the current year, having secured impressive victories in his previous two outings. The Brazilian earned early knockout finishes against Rafael Fiziev and Michael Chandler.
In the main event of UFC 331, reigning flyweight champion Joshua Van and former champion Alexandre Pantoja will face off in a rematch.
This is a high-stakes comeback for Tsarukyan, as following a long layoff, he will step into the ring against an opponent who has built significant momentum this year. Ruffy's recent knockouts show that the Brazilian poses a serious threat.
Although bookmaker odds make Tsarukyan a clear favorite, psychological and physical preparation in the ring will be decisive. The outcome of this fight will show how ready the Armenian fighter is to maintain his position among the top contenders in the lightweight division.
