According to a report by The Wrestling Observer, current
UFC Heavyweight Champion
Randy Couture (who is also in a legal battle with the company as well) stated on the Bubba the Love Sponge radio show earlier today that he is trying to get a submission grappling match set up with TNA World Champion Kurt Angle.
Angle has stated in previous interviews that he was hoping to set up a fight with Couture later this year, although he gave the impression it would be an MMA fight and not a "submission grappling rules" match.
