UFC lightweight Dustin Poirier said something, but he didn’t say much.

On Wednesday, news broke that Poirier  (24-5 MMA, 16-4 UFC) suffered an injury, forcing the cancellation of his UFC 230 lightweight fight against Nate Diaz. The nature of the injury was not revealed, however.

And it’s still a mystery after Poirier issued a statement Thursday, calling it a “small setback” but offering no details (via Twitter).

Small setbacks happen.. I’m flying out to LA next week to get a second opinion on my injury and I’ll have an idea of when I can return to compete, I can’t wait to get back in the Octagon!!

Thank you all for the support

UFC 230 takes place Nov. 3 at Madison Square Garden in New York. The main card airs on pay-per-view following prelims on FS1 and UFC Fight Pass.

Poirier (24-5 MMA, 16-4 UFC), No. 3 in the latest USA TODAY Sports/MMAjunkie MMA lightweight rankings, was going to fight for the fourth time in a year. “The Diamond” has won three consecutive event headliners by knockout, stopping former UFC champ Anthony Pettis, former WSOF champ Justin Gaethje and, most recently at UFC on FOX 30, former UFC and Bellator champ Eddie Alvarez.
