Kell Brook will have to fight Devon Alexander in the US if he doesn't vacate the IBF title

Devon Alexander: Unlikely to defend his IBF welterweight title outside of the US

They are the thoughts of Alexander's trainer Kevin Cunningham, who has expressed his surprise that Brook - now the mandatory challenger for the title - has had so little exposure in the States.

"It'll have to happen in the States," Cunningham told livefight.com. "No way is Devon going to England. We have no problem taking the fight but Devon has no reason to go over there. No-one knows Kell over here.

"You'd have thought his promoter would've got him over more than just the once to gain him some notoriety."

There are a number of fights - with or without the title - that would arguably make more money for Alexander in a stacked welterweight division.

However, Team Alexander plan on defending the belt and that means a showdown with Brook in 2013.

"He's now a two-weight world champion but we'll sit down with the rest of the team to discuss the options," Cunningham concluded. "We don't plan on vacating the title and if Kell Brook wants it then he and his team can come and get it."

According to reports, the teams have until November 22 to make the fight before it goes to purse bids.
