Even without a major belt at stake, Brian Castaño and Wale Omotoso behaved like true junior middleweights.

Both boxers came well within the 154-pound divisional limit for their scheduled 10-round non-title fight, which headlines this weekend’s edition of Premier Boxing Champions (PBC) on FS1 live from MGM National Harbor in Oxon Hill, Maryland (Saturday, FS1, 10:30pm ET).

Argentina’s Castaño (15-0-1, 11KOs) showed up to Friday’s weigh-in at a combat fit153.6 pounds for his first post-title reign bout. Omotoso (28-4, 22KOs)—a Nigeria-born puncher now based out of California—weighed in at a trim and ready 152 pounds for his fourth straight bout in the division after having previously campaigned as a welterweight.

Castaño enters a fight without a major title around his waist for the first time in more than three years. The 30-year old from Buenos Aires has laid claim to at least some portion of the junior middleweight crown since a Nov. 2016 knockout win over Emmanuel de Jesus, enjoying three combined defenses of two different versions of the title—including a 12-round draw with Erislandy Lara in March—before having to relinquish his strap this past summer. Failure to comply with a mandatory title fight rematch with France’s Michel Soro brought an anticlimactic end to his reign, though he views Saturday as the starting point for a second title run.

Omotoso enters on the heels of a career resurrecting knockout win over fellow veteran contender Curtis Stevens this past August. All four of his career losses have come within his last nine starts, although he has won two of his past three starts since returning earlier this year.

In the evening’s chief support, Javier Fortuna and Jesus Cuellar collide in a battle of former titlists. The two collide for a regional lightweight title, with both coming well below the 135-pound limit.

Fortuna (34-2-1, 23KOs)—a former two-division titlist from Dominican Republic who now lives and trains in the greater Boston area—weighed 133.2 pounds for the contest. Argentina’s Cuellar—a former featherweight titlist—weighed 133 pounds.
