Fans will have to wait a little longer for Nate Diaz ‘s return to the octagon after he declined a fight against a former UFC title challenger. The younger Diaz brother has amassed a large following since capitalizing on his victory over Conor McGregor nine years ago. Since then, many fans have been eagerly awaiting each time the Stockton native makes the walk to the cage again, and while rumors are heating up about a potential UFC return , the 40-year-old’s supporters now face yet another setback. Despite having an opponent and date ready for his return, Nate Diaz reportedly refused to sign the contract against a fellow UFC veteran. Former UFC welterweight title challenger Darren Till has posted a revealing message on his social media, insisting that Diaz is just one of many who are refusing to fight him.
