WILMINGTON, Mass. -- Add David Warsofsky to the list of injured Bruins defensemen.

Warsofsky did not practice with the team Friday morning at Ristuccia Arena, and coach Claude Julien said he expects Warsofsky to be out "a while" with an undisclosed injury.

Warsofsky logged 15 minutes of ice time during Thursday's 5-2 win over the Edmonton Oilers at TD Garden. Warsofsky joins Zdeno Chara (knee), Torey Krug (finger) and Kevan Miller (shoulder) as the team's injured blueliners. Krug practiced with the team Friday and said afterward he hopes to be back in the lineup soon.

"It's doing well," Krug said. "It's coming along nicely and made some good progress the last couple of days. It's great to be back on the ice with my teammates, and competing and everything like that. It's feeling better, that's for sure."

Miller was on the ice prior to the team's practice and is progressing.
