Oilers' Zack Kassian (concussion) active for Saturday night's game vs. Flames

Oilers winger Zack Kassian will suit up Saturday night after missing Edmonton’s season opener while in concussion protocol, the team announced (Twitter link). He suffered the injury in a fight late in the preseason when his helmet came off. To make room for Kassian, Edmonton has placed forward Devin Shore on IR with an undisclosed injury, notes Daniel Nugent-Bowman of The Athletic (Twitter link). The placement is retroactive to last Saturday, which means he’ll have missed seven days already, which means Shore could be activated as soon as Tuesday’s game against Anaheim.

Other injury notes from around the NHL:

• Islanders goaltender Semyon Varlamov missed training camp due to nagging soreness, with head coach Barry Trotz expressing optimism that the veteran wouldn’t miss much time. However, Newsday’s Andrew Gross relays that while the netminder took a few shots at the end of practice on Friday, there remains no timetable for a return. Trotz ruled out the possibility of a conditioning stint, but it remains unclear when Varlamov will actually be able to suit up for New York.
• Lightning defenseman Cal Foote is roughly a week away from returning, notes Eduardo A. Encina of the Tampa Bay Times (Twitter link). He had surgery last month to repair a torn tendon in his hand, which caused him to miss all of the preseason. Accordingly, it wouldn’t be surprising if Tampa Bay asked him to start with a short conditioning stint first; he’d have to agree to the move as he’s no longer waiver-exempt.
• The Penguins have ruled out winger Bryan Rust for Saturday night’s game against Chicago, head coach Mike Sullivan told reporters including Mike DeFabo of the Pittsburgh Post-Gazette. The 29-year-old was injured early in the third period on a hit from Florida’s MacKenzie Weegar on Thursday. Pittsburgh is still evaluating Rust’s injury so there’s no timetable yet for his return although he has been placed on IR.
• Vince Dunn will miss Saturday night’s game for the Kraken, relays Ryan S. Clark of The Athletic (Twitter link). The blueliner is listed as day-to-day with an undisclosed issue. Haydn Fleury will take Dunn’s place in the lineup.
• The Kings announced (Twitter link) that they’ve activated defenseman Olli Maatta off injured reserve. He’ll take the roster spot of Christian Wolanin who was claimed off waivers earlier Saturday by Buffalo. The 27-year-old had a sparing role with Los Angeles last season, logging less than 17 minutes a game in 41 appearances while recording just four assists.
