Reigning UFC light heavyweight champion Daniel “DC” Cormier and former divisional kingpin Jon “Bones” Jones possess one of the deepest rivalries the sport has ever seen, and they’ve never been afraid to show it.

Having already faced off once at January 2015’s UFC 182 where Jones successfully defended his then held title, the two were scheduled to rematch at the upcoming UFC 197 on April 23, 2016.

Cormier, however, unfortunately suffered an injury and was forced off of the card, leading the UFC to call on No. 6-ranked Ovince St. Preux to face Jones on short notice for the interim 205 pound strap.

Speaking on the replacement bout, “DC” feels as if St. Preux could be in for a tough test.

Despite their obvious bad blood, Cormier did admit that, in his opinion, Jones is the greatest fighter of all-time:

“I never downplay what Jones is to this sport and what he’s been to this sport,” Cormier told Damon Martin of FOX Sports. “As a competitor I have to be honest with myself, this is a tough one for Ovince. He’s obviously a big, long guy that could cause some issues for most people, but Jon is who he is for a reason.

“He’s the greatest fighter to ever put on a pair of gloves.”

In the wake of his withdrawal from UFC 197, Cormier even was far as to offer his training camp to OSP, or in other words, he offered St. Preux a free trip to San Jose to train at the American Kickboxing Academy.

St. Preux would ultimately decline, but “DC” also admitted that he ‘doesn’t know how’ to beat Jones, given the fact that he lost the first bout, although he obviously would’ve helped OSP in any way he could’ve:

“”Even if I don’t help Ovince Saint Preux and I can’t help him beat Jon because I don’t know how to beat Jon Jones, I didn’t do it,” Cormier said. “I don’t have some secret serum to give Ovince, but I would try to help him because even by me being there, it bugs him.”

Will “DC” find a way to beat Jones, or will the outcome of the inevitable rematch not differ from the first showdown?
