The two-time WBO super-featherweight champion was hoping to get his career back on track following a knockout loss to Mikey Garcia in November, but the Puerto Rican will have to wait a little longer to do so.
Martinez’s replacement will be Canadian-based Arash Usmanee, who drew last time out when challenging Argenis Mendez for the IBF super-featherweight title in New York in August 2013.
Usmanee, 32, has dropped just one bout in 22 outings since turning pro in 2009, in what was a hotly debated unanimous decision defeat to Rances ‘Kid Blast’ Barthelemy in January of last year.
Standing in his way of a first victory since June 2012 will be the disgruntled Beltran, who is still reeling from shock at not getting the verdict when putting in a great shift against Ricky Burns for the WBO lightweight title seven months ago.
Burns has since lost his belt to Terence Crawford, and the winner of this weekend’s clash at the MGM Grand in Las Vegas will be hoping to challenge for the unbeaten American’s new title later in the year.
