Ryan Pulock left Saturday's game early and is dealing with a lower-body injury, and goalie Marcus Hogberg may also potentially be hurt.

With the Islanders’ playoff hopes hanging by a thread, Romanov and Scott Mayfield — who will spell Dobson on the top pair — will be shouldering a huge burden starting with Friday’s match at UBS Arena against the Flyers.

Tony DeAngelo’s first morning on Long Island consisted of a quick skate, a short introduction to his new teammates and getting ready to play in his first game in the new digs.

Dobson (lower body) was designated for injured reserve Friday, Stefen Rosner of NHL.com reports. Dobson was riding a three-game point streak prior to getting hurt but will now have to wait at least a week before rejoining the lineup.

Noah Dobson is out week to week for the Islanders because of a lower-body injury that will not require surgery. The defenseman was injured on a hit by Columbus Blue Jackets forward Cole Sillinger at 1:14 of the third period during a 3-1 win Monday. Dobson left under his own power but did not return.

If Pulock is going to be out for a bit, the Islanders are likely to recall right-shot defenseman Grant Hutton from Bridgeport. The 29-year-old has played in 13 games for New York this season with two assists while averaging 13:28 minutes per game.

Romanov leads the Islanders with 75 hits, 6.43 hits per 60, while also leading in blocks per 60, with 6.26, while averaging the third-most minutes at 21:51 per game. With Noah Dobson now out due to injury and with no timetable for his return, Romanov will be heavily relied upon to carry out some of the workload.

New York Islanders defenseman Noah Dobson (lower body) has been placed on IR due to an injury suffered on Monday against the Columbus Blue Jackets. Dobson will be sidelined week-to-week, but his injury will not require surgery.

The Islanders are playing their best hockey of the season, but they are facing as bad an injury crisis as they’ve had in a season filled with them.
