Yuriorkis Gamboa is jumping weight from Featherweight to Lightweight to meet former champion Brandon Rios, who had to vacate his title during his last outing after failing to make weight after three attempts and despite talk that he would be making a permanent move to Super Lightweight.

From Kevin Iole of Yahoo! Sports:

Gamboa, 30, will be jumping two weight classes to meet Rios, who had been expected to jump from lightweight to super lightweight after his last fight. Rios, 25, lost his WBA title on the scales on Dec. 2 in New York when he failed to make the 135-pound limit for a Dec. 3 title defense against John Murray.

His weight-cut problems were documented in the debut of a new feature done by HBO Sports that aired first on Feb. 4, “2 Days: Portrait of a Fighter.” HBO had behind-the-scenes footage of Rios’ struggles to attempt to make the weight, which he ultimately failed to do three times. The fight went on, with Rios (29-0-1, 22 KOs) winning by 11th-round stoppage, though he had to surrender his belt because he did not make weight.
