After the Bruins visit the Sabres they host the Florida Panthers on Monday and visit the Washington Capitals on Wednesday.
In the five games Chara has been sidelined, the Bruins have allowed nine goals. They allowed three goals the past two games without Chara and defenseman John-Michael Liles, out indefinitely with a concussion.
Center Patrice Bergeron did not practice with the Bruins on Friday. Julien said Bergeron was home and would meet the Bruins at their plane. Bergeron is not injured, according to Julien.
In search for a lineup spark awaiting Chara's return, the Bruins recalled forward Anton Blidh from Providence of the American Hockey League on Friday. He practiced on the fourth line with center Dominic Moore and right wing Jimmy Hayes. Blidh, 21, the Bruins sixth-round pick (No. 180) in the 2013 NHL Draft, is known more as an energy player, has nine points (four goals, five assists) in 19 games for Providence this season.
"He's playing well," Julien said of Blidh. "So we brought him up. We'll get to see him hopefully [Saturday]."
Forward Noel Acciari, who skated as a fourth member of the fourth line Friday, will miss his 13th straight game with a lower-body injury. Acciari, like Chara, is getting close to returning.
