UFC 187: Injured Khabib Nurmagomedov out of bout with Donald Cerrone

More bad news fight fans. UFC 187 has just lost another marquee attraction.

Khabibi Nurmagomedov, the #2 ranked UFC Lightweight, has been forced to withdraw from his bout with Donald Cerrone on May 23 according to a report by MMA Junkie. Citing an anonymous source "close to the fighter" but unable to speak on the record because "they are not authorized to discuss such matters," Junkie's John Morgan went live with the story this evening.

"While the exact nature of the injury wasn't immediately revealed, additional sources indicated Nurmagomedov's knee was the culprit. An exact timetable for his return wasn't established," Morgan wrote.

ESPN's Brett Okamoto confirmed the news.

He was previously booked to face Cerrone at UFC 178 in September of last year but had to pull out with a knee injury. He has not fought since April of last year.
