Blues forward Vladimir Tarasenko will not take a trip with the group for weekend games at Boston and Detroit after suffering an unspecified upper-body injury in a win over Los Angeles.

Basic manager Doug Armstrong said Friday that Tarasenko will be re-evaluated when the team returns following Sunday's game versus the Red Wings.

Tarasenko left Thursday night's 5-2 win over the Kings after getting tangled up with Kings defenceman Sean Walker on a partial break with about 6 minutes left in the very first. Tarasenko, who had eight points in his previous five games, had 2 shots in 4:37 of ice time before leaving.

"He's a crucial leader for us and it's hard to see him decrease," goaltender Jordan Binnington said after the video game. "I think our group did a great job of reacting and selecting each other up. "
