UFC 173 has a late addition to the lineup, and it’ll serve as the Memorial Day weekend’s pay-per-view co-headliner.

The UFC today announced Daniel Cormier (14-0 MMA, 3-0 UFC) will put his undefeated record on the line against veteran Dan Henderson (30-11 MMA, 7-5 UFC). UFC President Dana White made the initial announcement on “SportsCenter.”

UFC 173 takes place May 24 at MGM Grand Garden Arena in Las Vegas. In addition to the PPV main card, prelims are available on FOX Sports 1 and UFC Fight Pass.

Cormier is ranked No. 6 in the latest USA TODAY Sports/MMAjunkie MMA light-heavyweight rankings. Henderson is a spot behind at No. 7.

Cormier, a significant favorite in the bout, recently made short work of injury replacement Patrick Cummins at UFC 170. It marked the light-heavyweight debut for the former Strikeforce heavyweight grand prix winner. Cormier, an Olympian and former NCAA Division I All-American wrestler, now has nine stoppages in 14 career wins. White suggested a victory over Henderson would put the 35-year-old in prime position for a title shot, though Glover Teixeira and Alexander Gustafsson are first up for champion Jon Jones.

Henderson, meanwhile, also is looking for an elusive UFC belt. The former two-division PRIDE champion recently halted a three-fight losing streak with a knockout win over Mauricio “Shogun” Rua in UFC Fight Night 38’s headliner. The 43-year-old, who’s also a former Olympian and collegiate wrestling standout, faced a likely release (and possible retirement) if he didn’t pull off the win. A victory over Cormier would be a significant one for the veteran fighter, who competes for the first time since ending testosterone-replacement therapy.
