Aung La N Sang-Shamil Erdogan rematch joins stacked ONE 171: Qatar on Feb. 20

Former double ONE world champion Aung La N Sang is set to return to action next month in a rematch with Turkish fighter Shamil Erdogan. They will square off in a middleweight MMA showdown at ONE 171: Qatar on Feb. 20 at the Lusail Sports Arena.

The fight will be a rematch, as their first encounter came back in September in the United States, where the Dagestani native beat the 'The Burmese Python' by TKO in the second round.

Aung La N Sang, 39, who used to hold simultaneously the ONE welterweight and light heavyweight MMA world titles, is seeking to bounce back from his previous defeat to Erdogan as well as notch his 15th victory in 19 matches in nearly a decade of competing under ONE Championship.

Prior to losing to Erdogan, the Kill Cliff FC standout was riding a three-fight winning streak, with all of those victories coming by way of finish.

Erdogan, 34, for his part, has won his first two matches in ONE and has an overall undefeated professional record of 10-0.
