In the top non-televised undercard bout, Ryan “The Irish Outlaw” Coyne (21-0, 9 KOs), from St. Louis, and Marcus Oliveira (24-0-1, 19 KOs), from Lawrence, Kan., will collide in a battle of unbeatens in a WBA light heavyweight elimination bout. The two were to have met on the undercard of Bernard Hopkins vs. Tavoris Cloud on March 9 before Coyne suffered a cut during training that resulted in a postponement.
The winner of Coyne vs. Oliveira, scheduled for 12 rounds, will become the No. 1-ranked light heavyweight by the WBA and the mandatory challenger to its champion, Beibut Shumenov.
Coyne gained attention while campaigning as a cruiserweight when he was chosen to participate in the fourth season of The Contender. He made it to the semi-finals before suffering an accidental headbutt that forced him to leave the competition. In his final fight at cruiserweight, Coyne captured the World Boxing Council United States Championship with a unanimous decision over the previously undefeated David McNemar on June 25, 2011.
Coyne is 3-0 since moving down to the 175-pound limit in October 2011.
Oliveira has shown considerable power by winning 19 of his 25 matches by knockout, a 76% knockout ratio. He scored a pair of third-round knockouts in fights against his most notable opponents: former cruiserweight world champion Kelvin “Concrete” Davis in 2008 and Antwun Echols on Jan. 28, 2012.
