Teen Paralyzed While Playing High School Hockey A high school student in Minnesota severed his spinal cord while playing hockey, MyFox9.com reported. Jack Jablonski, 16, a junior varsity player at Benilde-St. Margaret's in St. Louis Park, Minn., Friday night when an accidental check from behind left him paralyzed. Doctors initially thought the teenager suffered a bruised spinal cord and broken vertebrae, but have now diagnosed him with a severed spinal cord. It's unclear if Jack will be able to walk again. The Minnesota State High School League sent a note Tuesday to hockey coaches and school officials, which urged them to review safety practices with teams. Among the recommendations, the league said coaches should remind players to eliminate checking from behind, be grateful when officials enforce rules that make the game safer; officials should emphasize appropriate contact and checking; and players should hit the brakes when they see the numbers on the back of a jersey.
