Alexander Steen will be out at least four weeks for the St. Louis Blues with a left high ankle sprain.
The forward was placed on injured reserve Thursday and returned to St. Louis from the Blues' road trip. He will be re-evaluated in four weeks.
Steen left a 5-2 win against the Edmonton Oilers at Rogers Place on Wednesday with 29 seconds remaining in the second period after colliding with Oilers forward Alex Chiasson. Steen has five assists in 17 games this season and 610 points (238 goals, 372 assists) in 980 regular-season games for the Toronto Maple Leafs and Blues.
The Blues (11-3-3) are also without forward Vladimir Tarasenko, who is out at least five months after having surgery on his left shoulder Oct. 29.
St Louis has won six consecutive games coming off the first Stanley Cup championship in its 51-season history. They play the Calgary Flames at Scotiabank Saddledome on Saturday (10 p.m. ET; ESPN+, CBC, SN, SN360, SN1, CITY, FS-MW, NHL.TV).
