UFC on ESPN 31 has lost a marquee heavyweight bout.
A person with knowledge of the matchup confirmed the news to MMA Junkie on Tuesday but asked to remain anonymous because the promotion has yet to make an official announcement.
Boser addressed his withdrawal on social media but did not specify a reason.
“Sorry guys. I hope to have this resolved soon,” he tweeted.

Boser (20-8-1 MMA, 4-3 UFC) was looking to continue riding the momentum from his second-round knockout of Ovince Saint Preux at UFC Fight Night 190 in June, which snapped a two-fight losing skid.
Meanwhile, Pavlovich (14-1 MMA, 2-1 UFC) was set to make the walk for the first time in over two years. The 29-year-old Russian hasn’t competed since his first-round finish of Maurice Greene in October 2019.
