Bogosian, who is scheduled to become an unrestricted free agent this summer, has been a member of the Sabres for parts of six seasons. Injuries have limited the 29-year-old to 243 games in that span, including 65 contests last season.
In spite of his injuries, Bogosian was a prominent figure in the dressing room (he served two seasons as an alternate captain) and worked actively to give back to the community through his BOGO Bunch foundation and Tickets for Troops program.
"Honestly, I do have the organization and the team to thank for the relationship I was able to create by being here with him," Sabres captain Jack Eichel said.
"… Obviously, we play a game and everything but at the end of this, whenever the two of us are done playing, he'll be a lifelong friend of mine. … There's not many people in the world that I'm closer with. We have a really special relationship."
The Sabres recalled John Gilmour to round out their group of seven defensemen prior to Saturday's practice. Krueger said the decision was based on both Gilmour's comfort with the group - he broke camp with the Sabres in the fall and appeared in four contests - and wanting to allow Lawrence Pilut, who was assigned to Rochester on Friday, to continue appearing in games.
The Amerks play tonight in Syracuse, then host Utica tomorrow afternoon.
