At 26 years old, Zach McKelvie is the oldest player at Bruins rookie camp. But the reason he's arrived so late to the party is because he was fulfilling his duties as an active member of the U.S. Army.

A 2009 graduate of West Point, the Bruins originally signed McKelvie in the hopes that the Army would release him from his commitment to pursue a pro hockey career. That permission did not come until this summer, but McKelvie is ready to try and shake off the rust and make up for lost time.

Bruins assistant general manager Jim Benning said that McKelvie might be a bit behind because he hasn't played competitive hockey in two years, but he isn't concerned about McKelvie's future because he is a terrific skater and a very competitive player.
