BOSTON - Paul Postma knew he would be a role player when he signed with the Bruins over the summer. With a deep defensive corps and plenty of young talent on the horizon, he was prepared for the chance that his playing time would be scarce.
But, as Postma said Saturday morning, injuries are part of the game and his job is to be ready to go at any time.
And now, with Adam McQuaid sidelined for up to two months with a broken right fibula and Kevan Miller a game-time decision, Postma's chance has come. The 28-year-old right shot defenseman will make his Bruins debut on Saturday night against the Buffalo Sabres at TD Garden.
"I kind of knew that would be my role coming into this year," said Postma, who played his first seven seasons in the Winnipeg organization. "This is a deep defensive corps with a lot of good players. Injuries are part of the game and we have a few right now. It's time for guys like me to step up and I'll be ready."

Sitting out the first six games of the season is not an easy task, but Postma has tried to keep himself in the best shape possible and said he'll be looking to keep things simple.
"Play to my strengths, keep my feet moving, use my speed, good first outlet pass, be strong defensively," said Postma. "Try to get the puck to the net. There's so many things…when you get out there you try not to think too much. Just go out there and play hard and have fun."
With some of the question marks on the back end, the B's pairings against the Sabres are still to be determined.
"I have no idea who I'm playing with, what the situations gonna be," said Torey Krug. "But that's what organizational depth is all about. We're confident that he's been put the wringer. Obviously he hasn't seen any game action yet, but practices he's getting a lot of reps and he's part of this team so I'm sure he'll be excited to go if he gets the nod. We'll see how it goes down."
If Miller is unable to suit up against Buffalo, Rob O'Gara will likely make his season debut. The 24-year-old, one of the final cuts of training camp, was recalled on an emergency basis Saturday morning.
O'Gara has one assist and a plus-2 rating in three games for the Providence Bruins this season. The 2011 fifth-round pick played in three games for Boston last season.
Cassidy termed David Krejci as a game-time decision with an upper-body injury, suffered against the Vancouver Canucks on Thursday night.
"I got hit in my upper-body last game," said Krejci. "Trying to get back…it's a brand new injury, it just happened the other day in the game…I don't think this is an injury that will be long-term. It was one of these things that happens. I really feel like it's day to day."
Cassidy does not expect the team to recall anyone from Providence should Krejci be unable to play.
"We'll move some guys around," said Cassidy. "[David] Backes and [Tim] Schaller have played center over the years. [Patrice Bergeron] will play. I think we'll be OK."
