John Klingberg is expected to be out 2-4 weeks for the Dallas Stars because of a lower-body injury.
The defenseman was injured when he was hit in the neck area with a shot before twisting and falling to the ice in the second period of a 4-1 win against the Colorado Avalanche at American Airlines Arena on Tuesday. Klingberg was helped off by a trainer and returned to finish the period but did not come out for the third.
He had an MRI on Wednesday and will be re-evaluated in two weeks.
Forward Roope Hintz, who sustained a lower-body injury in a 4-1 win against the Montreal Canadiens on Saturday, is likely to miss at least three more games and and is not expected to return before Nov. 16, when the Stars play at the Edmonton Oilers.
Defenseman Andrej Sekera, who has missed four games with an upper-body injury, is expected to return when Dallas visits the Winnipeg Jets at Bell MTS Place on Sunday (2 p.m. ET; TSN3, FS-SW, NHL.TV).
Defenseman Roman Polak, who has missed 16 games after fracturing his sternum in the season-opener against the Boston Bruins on Oct. 3, returned to practice on Thursday and is expected back in the lineup at some point during Dallas' upcoming four-game road trip.
The Stars (8-8-1) have won four in a row and seven of eight after a 1-7-1 start.
