Justin Falk has a fresh cut under his right eye. Other than that, Buffalo’s defensemen are healthy.

That’s a rarity.

The Sabres have had their full complement of defensemen just eight times this season. It hasn’t happened since Nov. 1, but it is possible coach Dan Bylsma will have everyone at his disposal Friday when the New York Islanders visit KeyBank Center. Eight blue-liners practiced Thursday, which will give Bylsma choices on which six to dress.

“As a team, it’s great,” defenseman Taylor Fedun said in HarborCenter. “We’ve had some key injuries back there. It’s definitely a good problem for us to have going forward here.”

Fedun (upper body) and Zach Bogosian (knee) practiced with the team for the first time since suffering their injuries. They joined Rasmus Ristolainen, Jake McCabe, Dmitry Kulikov, Josh Gorges, Cody Franson and Falk.

Bogosian and Fedun were going to talk with the medical staff to determine their return dates. If Bogosian is ready, it’s possible Falk or Fedun will return to Rochester. The other could stay as the seventh defenseman.
