Last night in Edmonton during the Blackhawks versus Oilers game, former Blackhawk Duncan Keith took a violent fall into the end boards, leaving him unconscious on the ice. The fall occurred when Keith got his skate tied up with Sam Lafferty. The fall left Keith vulnerable as he struck the end-boards back first.
Today the Oilers announced that Keith had entered NHL concussion protocol, but that the veteran defenseman had also sustained an upper-body injury on the play. The timeline for Keith's return was set at 1-2 weeks, but that is pending his removal from the NHL's concussion protocol.
