BUFFALO -- Buffalo Sabres defenseman Zach Bogosian will be out 4-6 weeks with a lower-body injury sustained at practice Wednesday.
Bogosian was injured when he got tangled up in a battle for a loose puck with forward Evander Kane in the corner and went down. Bogosian needed help leaving the ice and was unable to put any weight on his left leg.
"It was weird," Kane told the Sabres website following practice. "We were just kind of battling, got tangled up and we were both falling. Obviously he was in some discomfort, and it was kind of a freak accident."
Justin Falk replaced Bogosian in the lineup in a 3-1 win against the Columbus Blue Jackets on Thursday.
"It's a tough blow for him," Sabres coach Phil Housley said of Bogosian. "He's been fighting through injuries this year and it's difficult. It's how the business goes, it's how the game goes. It's unfortunate, but it's giving other players an opportunity."
Bogosian missed the first 25 games of the season with a lower-body injury sustained Sept. 29 in the Sabres' final preseason game against the New York Islanders. He had one assist and averaged 19:09 of ice time in 18 games this season.
"I think he was really, really good right when he got back, especially being out that long of a time stepping in," Housley said. "A lot of those games early on when he got back in, he was our best defenseman. Certainly we missed him up to that point just having the depth and what he brings day in and day out to the team. Moving forward here, it's a setback."
Bogosian, chosen by the Atlanta Thrashers with the No. 3 pick in the 2008 NHL Draft, was acquired with Kane by the Sabres in a trade with the Winnipeg Jets on Feb. 11, 2015.
Rookie defenseman Brendan Guhle, who was recalled Monday from Rochester of the American Hockey League and played his fifth NHL game Thursday, will get an extended look because of Bogosian's injury.
"I liked the way he played last game, just using his speed and mobility," Housley said of Guhle's performance during a 7-4 loss to the Jets on Tuesday. "We'll give him another opportunity tonight."
