I strained my lcl trying to gogo a guy in a tournament to get him to move. He put all his weight on me!!! Owwwww! Still beat him though but taught me a valuable lesson . . . I was flat on my back and in a bad position to even try the move. I don't blame rubber guard it was the way I was using it. However, you should talk to the doc. My LCL is still a little sore so I am training my weak side for a while.
