Aldo delays decision

Aldo, who suffered a rib injury while sparring last week, was initially expected to resume training on Tuesday and reveal whether he would defend his title in Las Vegas on July 11. 

But, according to numerous sources, the 28-year-old opted not to train on Tuesday and has instead delayed his training and decision to Friday. 

Should Aldo rule himself out, UFC have already called up Chad Mendes as a replacement and he will face McGregor for the interim UFC featherweight championship at UFC 189.
