Buffalo Sabres defenseman Mattias Samuelsson (lower body) has been listed as week-to-week. The 28-year-old sustained a lower-body injury Tuesday during preseason action after being hit by a puck. Buffalo will face Columbus in its season opener on Oct. 1, and there's a significant possibility Samuelsson might not be in the lineup. That would be a major blow for the Sabres after Samuelsson's breakout campaign in 2025-26. He recorded 41 points (13 goals, 28 assists), 109 SOG, 154 blocks, 132 hits, and a plus-41 rating in 78 games. Olen Zellweger (concussion) was also hurt this week, leaving two holes to fill on defense.

Columbus Blue Jackets defenseman Dante Fabbro (upper body) is uncertain for the season opener, The Athletic's Aaron Portzline reports. Fabbro was injured in Monday's preseason game against the Detroit Red Wings. On Wednesday, Blue Jackets head coach Rick Bowness told reporters that Fabbro's recovery "is going to be a little longer than we'd hoped." Columbus opens its season on Oct. 1 against the Buffalo Sabres, so Fabbro still has time to recover. With Damon Severson (shoulder) also racing to get healthy for the season opener, Columbus could already face selection problems. If the blue line isn't at full strength next Thursday, Denton Mateychuk would have an increased role.

Columbus Blue Jackets defenseman Damon Severson (shoulder) is questionable for next week's season opener, Aaron Portzline of The Athletic reports. Severson has been recovering from shoulder surgery since early April. At training camp, the team has steadily increased Severson's workload, but head coach Rick Bowness isn't sure whether Severson will be available on Oct. 1 against the Buffalo Sabres. Dante Fabbro (upper body) is also nursing an injury, giving trialist Carson Soucy a realistic shot at making the team. Meanwhile, Denton Mateychuk could have significantly more responsibility on defense early in the season.

Dallas Stars goaltender Jake Oettinger (lower body) was a late scratch for Wednesday's preseason contest against the Minnesota Wild and is questionable to suit up for Friday's rematch, Lia Assimakopoulos of The Dallas Morning News reports. According to Stars head coach Glen Gulutzan, Oettinger is dealing with some lower-body tightness. This doesn't appear to be a serious issue, and Oettinger is still on track to be Dallas' starter on opening night. The Stars kick off the campaign on Oct. 2 against the St. Louis Blues, giving Oettinger more than a week to shake off his lower-body issue.
