Dos Santos-Velasquez bout delayed?

It's unlikely that heavyweight champion Junior dos Santos will defend his title Sept. 22 in Toronto against former beltholder Cain Velasquez, UFC president Dana White said Saturday night during a postfight interview on Fuel TV.

"That fight will happen. I don't know when and I don't know where," White said shortly after UFC 147 in Belo Horizonte, Brazil. "It's going to depend on Junior.

"They're probably not going to fight in Toronto."

White did not specify a reason why the fight, which was slated for UFC 152, will likely take place at another event.
