Newly ‘belted’ UFC heavyweight champion Junior dos Santos has finished a successful knee surgery, repairing a torn meniscus suffered during his recent fight with Cain Velasquez at UFC on Fox 1. Now comes the rehabbing and then back to training the Brazilian. Dos Santos will be looking to make his first title defense against the winner of Brock Lesnar vs Alistair Overeem at UFC 141 on Dec. 30 at the MGM Grand Garden Arena in Las Vegas.
