The Chicago Blackhawks may be without forward Patrick Sharp for up to a month, according to CSN Chicago's source.

The report indicates that Sharp could miss four weeks with the apparent right-leg injury he suffered in a 5-0 victory over the Montreal Canadiens on Tuesday night.

Sharp left the game after taking a hit from Canadiens defenseman Alexei Emelin along the boards midway through the third period. After the game, head coach Joel Quenneville said Sharp may be "out for a bit."

Sharp has three goals and six assists in 13 games this season.
