Askren-Maia headlines UFC Singapore on Oct. 26

Two of the best pure grapplers in MMA history will face off in October.

Ben Askren will fight Demian Maia in the main event of UFC Singapore on Oct. 26, ESPN's Ariel Helwani confirmed with sources on Friday. Askren tweeted earlier this week that the fight was a done deal.

Askren is a former Olympic wrestler and two-time NCAA Division I wrestling champion at Missouri. Maia's background is in Brazilian jiu-jitsu, and he's one of the best ever to utilize that martial art in MMA. He's a former Abu Dhabi Combat Club grappling champion and International Brazilian Jiu-Jitsu Federation Pan American titleholder.

Both Askren and Maia are known for their phenomenal ground games.

Askren (19-1, 1 NC) was undefeated in MMA until he was knocked out in five seconds by Jorge Masvidal at UFC 239 last month. The Wisconsin resident is a former Bellator and ONE Championship welterweight champion.

Askren, 35, was acquired by the UFC via trade with ONE Championship for Demetrious Johnson last year and quickly made a name for himself with his quick-witted trash talk.

Maia (27-9) has won two in a row and nine of his past 12. The Brazilian fighter is coming off a majority decision win over Anthony Rocco Martin at UFC Minneapolis in June. Maia, 41, is a former UFC welterweight and middleweight title challenger with wins over the likes of Masvidal, Carlos Condit and Chael Sonnen.
