Noah Dobson had just starting heating up for the Islanders, but the defenseman is out indefinitely after suffering a lower-body injury.

The New York Islanders returned for practice one day after beating the Columbus Blue Jackets 3-1 on Monday night. During the game, Noah Dobson took a nasty-looking fall after a hit by Justin Danforth and did not return.

Noah Dobson has been the lone player in the Islanders’ top four who hasn’t dealt with injuries this season, but his status is a major concern after Monday night. Dobson left the 3-1 win over the Blue Jackets at the 1:16 mark of the third period with what appeared to be a leg injury after taking a hit from Cole Sillinger.
