The Bruins took Tuesday off after winning back-to-back games against Montreal Sunday and Monday.

When they report to practice Wednesday, they might be short two centers off their current training camp roster.

According to Bob McKenzie of TSN.ca, the Bruins have placed centers Trent Whitfield and Zach Hamill on waivers with the intention of assigning both to the Providence (AHL) farm club. Providence opened its training camp today.

Whitfield was an unrestricted free agent who re-signed with Boston over the summer. He was one of the team’s “Black Aces” after a solid half year in Providence that included recovering from a severe knee injury he suffered the prior summer. Hamill is in his fourth year of his entry-level deal and has yet to meet his potential after he was selected eighth overall in 2007. He has played in just four NHL games over the last two seasons.
