Perron has been out since suffering a concussion when he took an elbow to the head from Sharks forward Joe Thornton on November 4, 2010. He finished the game, but has not played since.
The 23-year-old Quebec native missed a total of 97 contests.
Perron wasn't cleared for physical activity until September, and wasn't allowed to join on-ice activity until late October. He was finally granted permission for full-contact drills the week before Thanksgiving.
A first-round pick of the Blues in 2007, Perron has totaled 53 goals and 131 points in 235 NHL games. He netted a career-best 20 goals two seasons ago and totaled a career-high 50 points in 2008-09.
