Former UFC heavyweight champion Andrei Arlovski received a short-notice call and said yes.
At UFC on ESPN 35, Arlovski (33-20 MMA, 22-14 UFC) will return to the cage as a replacement against Jake Collier (13-6 MMA, 5-5 UFC) after originally slated heavyweight Justin Tafa withdrew from the April 30 event for undisclosed reasons. The card takes place at the UFC Apex in Las Vegas and airs on ESPN/ESPN+.
Two people with knowledge of the matchup recently informed MMA Junkie of the booking but asked to remain anonymous as the promotion has yet to make an official announcement.
