I went to my new grappling school on Monday, and watched my friend from high school wrestling with UFC champion, Manvel Gamburyan. My friend caught him in an ankle lock, and wanted to let go, but Manvel told him to keep going. Bad idea. My friend pulled, and Manvel immediately tapped out in pain, and didn't grapple the rest of the night. We all hope it's nothing serious, but what happens if it is? Does that kind of stuff take a long time to recover from?
