I was playing in a golf tournament last Friday and I tore my rotator cuff. After a strong drive from one of my teammates,we all went to hit our second shot. My teammate hit his second shot and chunked it. I dropped a ball a few inches away and proceed to hit a shot with a 8 iron. I must have a buried sprinkler head. I hit it flush and you could hear the popping sound come from my shoulder area. It hurt like hell and I knew that it wasn't't good. I had injured my shoulder in college while on the baseball team. Seeing the doctor next week to determine my options. I have hit rocks but never anything like this.
