After losing his initial opponent, Chase Sherman has drawn an even bigger opportunity. Parker Porter has been forced out of UFC on ESPN 22 for undisclosed reasons, and Andrei Arlovski will step in on short notice to face Sherman on April 17. Both fighters confirmed the booking on social media Wednesday following an initial report from Fight Bananas . Former heavyweight champion Arlovski (30-20 MMA, 19-14 UFC) is still trucking at the age of 42 but will be looking to respond from a recent setback. After scoring back-to-back unanimous decision wins over Philipe Lins and Tanner Boser, Arlovski was submitted by Tom Aspinall at UFC Fight Night 185 in February
