Marc-Andre Bourdon was returned to AHL Adirondack on Sunday by Philadelphia. The Flyers have been busy shoring up their defense via trades before next week's deadline. The club acquired Pavel Kubina from Tampa Bay and Nicklas Grossman from Dallas, which prompted Bourdon's return to the minors. Bourdon has skated in 39 games with Philadelphia this campaign, while posting four points, 46 penalty minutes, 64 hits and 65 blocked shots.
