There's always some concern when a goalie takes a bump up high.
That's what happened Saturday in Pittsburgh as Penguins superstar center Evgeni Malkin charged toward the net and caught Chicago Blackhawks goalie Corey Crawford in the head with his thigh / posterior.
Crawford was examined by the trainer and left the ice, presumably at the behest of the NHL's concussion spotter.
He was, however, able to return shortly thereafter.
