Khamzat Chimaev takes on Tyron Woodley on September 5 at a wrestling event in Moscow organized by RAF. Both men held UFC championship belts at their peaks. Chimaev has been one of the welterweight division's most dangerous prospects, while Woodley was the 170-pound champion before falling down the rankings. The matchup pairs a rising force against a former titleholder trying to reclaim relevance. Neither fighter has had an easy path recently. Chimaev dealt with injuries that sidelined him through much of last year, though he returned to the octagon this year. Woodley has struggled to string wins together at welterweight and attempted a boxing career with limited success. This bout gives both men a chance to reset. For Chimaev, it's an opportunity to shake off the ring rust and remind people why he was once considered a future title contender. For Woodley, it's a chance to prove he still belongs in elite company at 170 pounds. A wrestling event rather than a traditional UFC card is an unusual venue for both, but the headline billing suggests promoters view this as a draw.
