The injury bug is biting hard among UFC lightweights.

A week ago, as we announced here at Caged Insider, Khabib Nurmagomedov was forced to pull out of his anticipated bout against Donald Cerrone, citing a knee injury. The two lightweight contenders were supposed to face off at UFC 187 on May 23, with the winner possibly receiving the next title shot against Rafael dos Anjos.

The turn of events prompted a little trash talk from former champion Anthony Pettis, who Nurmagomedov had implied was ‘suspiciously’ injury-prone earlier in his career.

Unfortunately for Pettis, it looks like the tables have again turned.

Today on FOX Sports Live, it was announced that Pettis has been forced to pull out of his upcoming bout against Myles Jury at UFC on FOX in July.

This time, the cause is an elbow injury. There are few details on the injury, and no timetable for Pettis’ return.

Edson Barboza has stepped in to face Jury at the event, which takes place on July 25 in Chicago.

Both fighters are coming off rare losses.

The 29 year old Barboza has earned a 15-3 record in MMA, noted mostly for his Muay Thai attack — featuring arguably, the division’s most potent leg kicks. But in his last bout was the victim of an upset at the hands of Michael Johnson, back in February at UFC Fight Night in his native Brazil.

The 26 year old Jury is 15-1 in MMA, and will look to bounce back from the first loss of his MMA career — at the hands (and feet) of Donald Cerrone. That bout took place back in January at UFC 152 in Las Vegas.
