Magnus Paajarvi will take the roster spot of Paul Stastny when the St. Louis Blues visit the Anaheim Ducks tonight.
Stastny was injured on his first shift of the Blues game Saturday night in Arizona.
The Blues have called it an upper body injury. Coach Ken Hitchcock called Stastny day-to-day.
Paajarvi, who appeared in 55 games with the Blues last season scoring six goals and 12 points, will be making his regular season debut.
