While the Sabres went through an hourlong workout on the main rink in HarborCenter, injured defenseman Zach Bogosian skated in full uniform with rehab and development coach Dennis Miller on the secondary rink.

“He’s ramping up his skating from being on the ice to being on the ice with gear,” coach Dan Bylsma said Sunday. “His skating level is going higher here. Hopefully, he continues to progress.”

Bylsma said there’s no timetable for Bogosian to start practicing with the Sabres. He has been out since suffering a sprained medial collateral ligament in his knee Nov. 1.

It’s been one month since forward Tyler Ennis had sports hernia surgery, an operation that could keep him out for two months.

“Ennis is doing real well,” Bylsma said. “He’s progressed off the ice. He could very well shortly get to skating, but it would be skating. It wouldn’t be with the team.”

The Sabres’ only other injury is a shoulder ailment for defenseman Taylor Fedun. He will miss his fourth game Tuesday when the Sabres host Los Angeles in KeyBank Center.

“Taylor Fedun is doing well, getting better, getting stronger,” Bylsma said. “There’s a possibility maybe after Tuesday’s game of getting on the ice.”
