A Michigan referee of an adult-league soccer match died Tuesday, two days after being punched in the head by a player, authorities said. John Bieniewicz, 44, died at Detroit Receiving Hospital from injuries suffered in what police said was an unprovoked attack. The blow left the victim unconscious and not breathing on the field, Livonia Police Chief Curtis Caid said. After the attack, the player fled the field and waved his middle finger at the crowd. Bieniewicz was in critical condition when he reached the hospital and was pronounced dead Tuesday morning.
