At the time of the injury, Green said Eklund would be sidelined an "extended" period of time, though he expected the 23-year-old to return sometime during the regular season.
Eklund has two points (one goal, one assist) in four games this season. Selected by the San Jose Sharks with the No. 7 pick in the 2021 NHL Draft, he has 165 points (51 goals, 114 assists) in 256 regular-season games with the Sharks and Senators, including three straight seasons with at least 15 goals and 45 points.
Eklund came to Ottawa in a trade with San Jose on June 23. He was acquired with forward Kasper Halttunen and the rights to forward prospect Brandon Svoboda for the No. 9 pick in the 2026 NHL Draft, which the Senators acquired from the Florida Panthers in the trade for forward Brady Tkachuk on June 21.
