Professor X vs Reed Richards

Reed and Xaiver have been kidnapped and depowered by Skulls. They are forced to fight each other (H2H) in a gladiator-style ring. They have no weapons and must fight until one of them is beaten to death. Both agree to the fight after the Skulls threaten to kill all of their loved ones. Who wins?

Xavier has military combat training but little experience in H2H. Any training or feats for Reed?

Reed Richard probably know how to use nerve strikes, that's the easiest way I see him winning
