The fight will headline UFC 292 on August 19 in Boston.
“Aljamain is an incredibly tough opponent. O'Malley has not yet been tested by high-class fighters, with the exception of the last fight against Yan, which was extremely close. So Sterling will be a big test for Sean. You can't "sleep" when you're fighting a champion.
I'm sure Sterling will win. He'll just pick up O'Malley. Aljaimein is an exceptional wrestler and phenomenal grappler. This is not the best match for Sean," Sandhagen said in an interview with ESPN.
