The practice mishap was so severe that Sypniewski’s shredded anterior cruciate ligament tore off his leg bone. The rare injury required major reconstructive surgery to repair the damage. Recently, Sypniewski underwent an arthroscopic cleanup procedure to follow up on the original surgery, according to his agent, Dave Butz. “It’s common for people to tear the ACL, but it’s not common for people to tear the bone where the ACL is attached,” said Sypniewski, who was sidelined last season on injured reserve. “That’s what I’ve been dealing with, trying to get used to the knee moving a little bit differently now.” Source: Carroll County Times
