UFC lightweight Bobby Green has announced he will be unable to compete in April’s UFC Fight Night: Mendes vs. Lamas event in Virginia.

Green was scheduled to fight Jorge Masvidal at the show, also known as UFC Fight Night 63, on April 4.

It was a disappointment for fans of Green, who were eager to see the Southern Californian in action again after a rare loss. Green, who is 29-6 in his MMA career and ranked ninth in the UFC’s official rankings, lost to Edson Barboza by decision back in November — snapping an eight-fight winning streak.

But his replacement, as announced by UFC officials (and first reported by FOX Sports) is another of the 155 lb elite — former UFC Lightweight Champion Benson Henderson.

Henderson is 21-5 in MMA, and is coming off two straight losses for the first time in his career.

This past weekend, former UFC Lightweight Champion Benson Henderson fought Donald Cerrone by unanimous decision at UFC Fight Night: McGregor vs. Siver.

That night, Cerrone was replacing Henderson’s original opponent, Eddie Alvarez who was forced to step away due to injury. In fact, Cerrone took the fight on less than two weeks notice. The fight was a listless affair, and many found the result inconclusive.

Masvidal is 28-8 in his MMA career and currently ranked #13 in the UFC rankings. Henderson is ranked fifth.

There is no word on the recovery time for Green.

UFC Fight Night: Mendes vs. Lamas is headlined by a bout between two featherweights, Chad Mendes and Ricardo Lama
