The NHL is looking into a claim by Alexandre Burrows that a referee made payback calls against him, and the Canucks are in support of their forward, according to an Associated Press report. The league said Tuesday that Colin Campbell, the NHL?s top disciplinarian, was reviewing the matter. Burrows accused referee Stephane Auger of targeting him in the Canucks? 3-2 loss to the Predators in Vancouver on Monday.
