With just five days left in the regular season, the defending Stanley Cup champion Chicago Blackhawks still haven't locked up a playoff berth. They'll try to take another step toward one on Wednesday, but they'll have to beat one of their biggest rivals to do so.

The Hawks, eighth in the West, host the St. Louis Blues at the United Center. Both teams have been off since Sunday, when the Blues routed the Blue Jackets 6-1 at Columbus while the Hawks lost 2-0 at home to Tampa Bay.
