Colorado Avalanche right wing Logan O'Connor (lower body) is day-to-day, Aarif Deen of Colorado Hockey Now reports. He sustained a lower-body injury in training camp, leaving O'Connor questionable for opening night. The Avalanche begin the action on Wednesday against the Los Angeles Kings. O'Connor has been a regular 20-point scorer for Colorado, but he played only 13 games in 2025-26 after hip surgery. Left wing Zachary L'Heureux (lower body) is also day-to-day heading into opening week, so Colorado could be missing two fourth-line grinders on Wednesday.

Columbus Blue Jackets defenseman Dante Fabbro (upper body) will miss the first month of the regular season, according to The Athletic's Aaron Portzline. On Sunday, Portzline reported that Fabbro is expected to be unavailable for "a month or more." A week ago, Fabbro suffered an upper-body injury in a preseason game, and the team placed him on Injured Reserve Friday. Regarding Columbus' defense, Damon Severson's (shoulder) availability at the start of the season is also in question. As such, the Blue Jackets are trying to sign Carson Soucy to a standard contract after he spent training camp with the team on a tryout deal.

Seattle Kraken right wing Mackie Samoskevich (upper body) will begin the 2026-27 campaign on Injured Reserve. He has dealt with an upper-body injury during preseason, and the team is set to start the regular season without him. In limited playing time, Samoskevich managed back-to-back 30-point seasons with the Florida Panthers, so it will be interesting to see what he can do in a larger role in Seattle. The Kraken plan to use him as a top-six regular. Alongside Samoskevich, Seattle placed center Jake O'Brien (lower body) on Injured Reserve Sunday.

Philadelphia Flyers goaltender Dan Vladar (upper body) fully participated in Sunday's practice, Jackie Spiegel of The Philadelphia Inquirer reports. Vladar had an injury scare last week in a preseason game, but he's on track to be ready for opening night. "I wouldn't say he's 100%, but he's very hopeful," Flyers head coach Rick Tocchet said. The Czech shot-stopper had an impressive first year with the Flyers and has a big role to play in the team's success. He finished the 2025-26 campaign with a 29-14-7 record, a 2.42 goals-against average, and a .906 save percentage.
