The Boston Bruins have added another body to their training camp roster by signing Peter Mueller to a professional tryout contract (PTO).

Mueller hasn’t played in the NHL since 2013 and has spent the last couple of years playing in Switzerland and Sweden. He is a 28-year-old center and was a former first-round pick in 2008.

He was drafted by the Phoenix (now Arizona) Coyotes and went on to play for the Colorado Avalanche and Florida Panthers.

PTO’s in hockey are commonplace, and the Bruins have usually had someone in training camp on one of these deals. Most recently (and notably), the club has Lee Stempniak in camp last year on a tryout, only to see him sign a contract with the Devils. The Bruins then traded for Stempniak at the trading deadline last season, a move that was heavily criticized.

If Mueller wants to make the team, he’s likely going to have to play on the wing, as the Bruins have too many centers and just signed Dominic Moore to compete for a spot on the fourth line.
