Forward David Perron has rejoined the St. Louis Blues more than 10 months after he was knocked out of hockey by a concussion.

Perron missed 72 games last season after a hard hit from the Sharks' Joe Thornton on Nov. 4 that resulted in a two-game suspension for the San Jose center.

Perron has spent months working on his recovery. There is no timetable for him to actually play.

Perron and Blues general manager Doug Armstrong said Monday that the winger started light exercises and skating 3-4 weeks ago because his symptoms have been relatively smaller and more infrequent.
