Less than one week after his 1-1 ride in the Alpinestars Legends Re-Match at the Rockstar Energy U.S. Open of Supercross, Mike LaRocco was out riding at Glen Helen last Thursday and apparently suffered a pair of broken arms, according to his friend Tim Ritchie of Red Bud. "The Rock" was riding in an open practice, came over and jump and there were two bikes laying right in front of him. The two-time AMA Motocross Champion broke one of his thumbs in three places, plus the wrist on his other arm. He is wearing a cast on both arms now. We'll let you know more when we hear more.
