Ottawa Senators defenceman Mark Borowiecki was on the ice for Friday's optional skate, but his return will not come in Game 4

Borowiecki said there's "still a little bit to go" in his recovery before he can play and admitted he suffered a setback since the first round injury.

His injury occurred halfway through the game when Burrows and Penguins defenceman Ian Cole got tangled up in front of the net causing Burrows to fall down hard. The 36-year-old appeared to hurt his left knee on the play and struggled to leave the ice under his own power. Burrows did not return to action. 

Burrows picked up one assist before his was forced to leave and had six goals with five assists over 20 games with the Sens during the regular season. 

Ottawa acquired Burrows a day before the Trade Deadline from the Vancouver Canucks for Jonathan Dahlen.

Ottawa is two wins away from advancing to the Stanley Cup Final for the first time since 2007. Game 3 will take place Wednesday night in Ottawa.
