ST. LOUIS - Blues forward Andy McDonald has returned to St. Louis to be evaluated for a possible concussion.
McDonald was hurt in the second period of a 3-2 loss Thursday night at Dallas. He was bumped from behind by teammate Nikita Nikitin, then hit in the head by the Stars' Vernon Fiddler.
He missed 24 games with a concussion last season after a hit Dec. 4 in Edmonton.
The Blues already have one forward sidelined with a concussion. David Perron has been out since last November, although he has resumed skating with the team.
