No he didn't. I've heard some theories and the best says that his rings are just decorations, and that his power comes from in the ornate gemstone on his belt buckle. Also in the bathroom scene when he tells Dave to hit him with his best shot he tells Dave to take the ring off, and right before Horvath cuts him off he says "it doesn't help me". So his power is only temporarily gone.
