Dunn (upper body) was placed on long-term injured reserve Monday.

Dunn won't be eligible to return until Nov. 12 against Columbus -- the move is retroactive to Oct. 17. Cale Fleury has been recalled from AHL Coachella Valley in a corresponding move. Dunn has picked up one goal, three points, 10 shots, 10 blocks and a minus-2 rating through four contests.

Wagner was sent down to AHL Colorado on Monday.

Wagner was called up by the Avalanche on Sunday, but he didn't see the ice in the team's win over San Jose. He'll head back to the AHL a day later, where he should see more consistent playing time.

Mintyukov (illness) participated in Monday's practice, Derek Lee of The Hockey News reports.

Mintyukov should be available to play Tuesday against San Jose after missing Sunday's 4-1 loss to the Kings. He has compiled two goals, three shots on net, six blocked shots and three hits in four appearances this campaign. With Mintyukov likely to play, Olen Zellweger might be a healthy scratch against the Sharks.

Head coach Greg Cronin said Monday that he anticipates Gibson (abdomen) accompanying the Ducks on their upcoming road trip, which begins Saturday against the Rangers, Derek Lee of The Hockey News reports.

Gibson has missed the first few weeks of the regular season while recovering from an appendectomy, but he appears to be closing in on a return. While it's not yet clear when he could be back in game action, it's encouraging that he'll travel with the team for the upcoming four-game road trip. Once Gibson is able to return, he'll likely compete with Lukas Dostal for the starting goaltender job.

Ullmark (strain) will return to the lineup in Tuesday's road matchup against Utah, Bruce Garrioch of Postmedia reports.

Ottawa hasn't announced a starter yet, but it wouldn't be surprising to see Ullmark back between the pipes following a three-game absence. He has earned a 1-1-0 record this campaign, stopping 53 of 58 shots.

Olofsson (lower body) was labeled week-to-week by coach Bruce Cassidy on Monday.

Olofsson was supposed to be getting a fresh start in Vegas but once again finds himself headed for a stint on the sidelines. At minimum, the 29-year-old winger, who has already missed two games due to his lower-body injury, figures to be out of action for at least the next three matchups. Given his recovery timeline, Olofsson is a strong candidate for injured reserve if the Knights need the roster spot.

Greaves was reassigned to AHL Cleveland on Monday.

Greaves' demotion ahead of Tuesday's clash with Toronto would seem to indicate that Elvis Merzlikins (upper body) will at least be healthy enough to serve as the backup against the Leafs. With youngster Daniil Tarasov having secured the No. 2 role in Columbus, it will take another injury or a trade of Merzlikins for Greaves to get another opportunity this season.

Greig (upper body) is a possibility for Tuesday's matchup against Utah, TSN 1200 Ottawa reports.

Greig was a full participant in Monday's practice. If he receives the green light to return from a three-game absence, he could occupy a bottom-six spot and get power-play time against Utah. Greig hasn't earned a point in two appearances this season. With David Perron (personal) away from the team, Cole Reinhardt might play Tuesday if Greig is unavailable.

Head coach Travis Green said Monday that Perron is away from the team due to a personal matter, TSN 1200 Ottawa reports.

Perron didn't participate in Monday's practice session, and it's not yet clear whether he'll be available for Tuesday's matchup against Utah. If the 36-year-old is unavailable Tuesday, Zack MacEwen could see an increased role for the Senators.

Robertsson (upper body) was activated from the injured non-roster list and loaned to AHL Springfield on Monday.

After being injured during training camp with the Blues, Robertsson will get to make his AHL debut. The 21-year-old forward registered two goals and four points in 27 regular-season games for Skelleftea AIK of the SHL in 2023-24.
