The St. Louis Blues officially activated forward Jori Lehtera from injured reserve Thursday, the club announced.
The 28-year-old missed the club's last four games due to an upper-body injury.
St. Louis waived forward Magnus Paajarvi in a corresponding move.
In three games this season, Lehtera hasn't recorded a point, but he collected 34 points in 79 games in 2015-16, and will be a welcome addition to the St. Louis forward corps.
