Former UFC welterweight champions Robbie Lawler and Georges St-Pierre have been rumored to be facing each other since July. The said speculations temporarily came to a halt when Lawler shut down claims about being offered a fight against GSP.

During Monday’s edition of The MMA Hour, the conversation was once again brought to the table when St-Pierre revealed that the UFC sent him a “letter” alluding to a possible fight against Lawler. But with no specifics indicated, such as the fight date and venue, St-Pierre simply dismissed it, bearing in mind that Lawler supposedly had issues of his own at the time.

"I knew Robbie Lawler had pulled out of the New York card,” St-Pierre told Helwani. “I don't know the reason he pulled out, but I heard in an interview with [Lawler's teammate] he needed a long break. So, the next day, my lawyer told me, 'Georges, now you're a free agent.'"

Lawler, for his part, immediately responded to St-Pierre’s comments in a recent interview with Brett Okamoto of ESPN.com. Lawler aired his side regarding his said health issues, while also issuing a challenge to St-Pierre.

"He says he was offered a fight against me but I wasn't healthy or whatever,” Lawler said. “He's basically trying to read between the lines like other people, not knowing what's the matter with me. Nothing is the matter with me.”

“Do you accept the fight or not? That's the real question, right? Because I'm ready to fight right now. Did you accept it or not? I'm guessing you didn't. Don't try to hide behind, 'I'm not healthy.' That's not the facts.”

"I'm always ready to fight that guy,” he continued. “I've been training my whole life to fight a guy like him -- and him, in particular. So don't use my name or try to hide behind something you think might be happening but is not. If he doesn't want the fight, shut up."

Lawler was originally slated to face Donald Cerrone at UFC 205 on November 12th in New York, but pulled out of the fight due to unspecified reasons.
