Early in the first period of the Toronto Maple Leafs' 4-2 victory over the Arizona Coyotes last night, defenseman Mark Giordano crashed hard into the end boards after diving to tip a puck on goal off the rush. Giordano attempted to get up briefly, but was unable to do under his own power.
Giordano looked dazed as he was helped to his skates by a trainer and teammate Morgan Rielly and did not return to the game. Following the game, Leafs head coach Sheldon Keefe was asked about Giordano's injury and was unable to provide much of an update as he stated that they "don't know the extent of it", but it does not sound like a short-term injury.
Reports have indicated that Giordano has likely suffered a concussion and given that the recovery from a concussion can vary from person to person, the expected timeline for a Giordano return is unknown at this time. It was Giordano's second game back with the team after being absent following the passing of his father.
