Utah Mammoth center Barrett Hayton (upper body) is week-to-week, Brogan Houston of the Deseret News reports. Mammoth head coach Andre Tourigny doesn't expect Hayton to play for a bit after he sustained an upper-body injury in Tuesday's loss to Edmonton. Hayton has tallied 25 points (10 goals, 15 assists) in 67 outings this season. His absence allowed Daniil But to re-enter the lineup on Thursday night against Washington, but he didn't make an impact in 9:08 of ice time.

Dallas Stars center Sam Steel (undisclosed) didn't finish Thursday's 2-1 loss to the New York Islanders, Mike Heika of the Stars' official site reports. He exited the action in the third period due to an undisclosed injury. Steel's ice time has increased throughout the season due to injuries, and it's helped him to record a career-high 33 points (12 goals, 21 assists) in 72 games. But he may now be sidelined himself. Fortunately for Dallas, Mikko Rantanen (lower body) is close to returning and will practice on Friday. Meanwhile, Michael Bunting, who was a healthy scratch on Thursday, is an option to rejoin the lineup for this weekend's back-to-back against Pittsburgh and Philadelphia.

New York Islanders defenseman Tony DeAngelo (lower body) will be unavailable for 1-2 weeks, the team announced. He sat out his first game of the season on Thursday night against Dallas and is expected to be sidelined for at least three more contests. Losing DeAngelo is a significant setback for the playoff-chasing Islanders. The 30-year-old has contributed five goals and 28 assists in 72 games. On the bright side, Ryan Pulock (lower body) was back on the blue line against Dallas, which helps ease the impact of DeAngelo's absence.

Columbus Blue Jackets defenseman Damon Severson suffered an upper-body injury in Thursday's 2-1 loss to the Montreal Canadiens, Jeff Svoboda of the Blue Jackets' official site reports. Severson scored the Blue Jackets' only goal of the game in the first period but left the action in the third. The 31-year-old has been very productive lately, recording three goals and two assists over the last five games. He has posted 32 points (eight goals, 24 assists) in 71 games for the season. Egor Zamula or Jake Christiansen will get a chance to play if Severson misses additional time, while Denton Mateychuk could be his replacement on the second power-play unit.
