Blues' injury woes continue as top-line winger Vladimir Tarasenko is out the rest of the regular season.

St. Louis Blues winger Alex Steen will miss at least four weeks because of a high ankle sprain.

Steen injured his left ankle in a collision with Edmonton's Alex Chaisson late in the second period of the defending Stanley Cup champions' 5-2 win over the Oilers on Wednesday night. The Blues put him on injured reserve Thursday, announcing he'd returned to St. Louis and would be re-evaluated in four weeks.
