Blues star Vladimir Tarasenko is leaving the postseason bubble in Edmonton to seek further medical evaluation on his injured shoulder, the team announced Tuesday.

Tarasenko will return to St. Louis to meet with team doctors for further evaluation of his left shoulder, which was surgically repaired in October 2019. He missed 61 regular-season games, but returned to training camp in July for the NHL's restarted season. The team says an update on Tarasenko's status will be available next Monday.

"It's concerning. Again, we don't know a lot yet. I'm not going to jump to conclusions about anything," Blues coach Craig Berube said.
