Head coach Travis Green said Friday that Eklund will be out for an extended period due to an ankle injury, Bruce Garrioch of Postmedia reports.
Eklund exited Thursday's game against the Flyers and was unable to put weight on his leg as he left the ice. A precise timetable for the 23-year-old's return hasn't yet been revealed, but he's considered out indefinitely and appears to at least be week-to-week at this point. Nick Cousins could see an increased role while Eklund is sidelined.
