Ottawa Senators goaltender Linus Ullmark (illness) should be available as the NHL season continues this week, Bruce Garrioch of the Ottawa Citizen reports. The Swedish netminder dealt with flu-like symptoms before the Olympic break and was unavailable for one game. Additionally, Ullmark has missed time this season due to personal reasons. He has posted a 16-8-5 record in 30 starts, allowing 2.86 goals with a .884 save percentage. Ottawa needs Ullmark to be at the top of his game to make the playoffs. The team resumes play on Thursday against Detroit, currently six points behind the final Eastern Conference wild-card spot.

San Jose Sharks right wing Ryan Reaves (upper body) was activated from Injured Reserve on Monday. The enforcer will be available for Thursday's matchup against the Calgary Flames. Reaves sustained an upper-body injury prior to the Olympic break but missed only one contest. In 46 outings this season, Reaves has contributed three goals while amassing 32 penalty minutes and 142 hits. He is tied for 29th in the league with 3.1 hits per game.

Buffalo Sabres center Josh Norris (ribs) will rejoin the lineup on Wednesday against the New Jersey Devils. The 26-year-old injured his ribs in mid-January and has missed 12 games. Norris has also missed time with an upper-body injury this season, appearing in only 19 contests. He has recorded six goals and 11 assists. Norris' return provides a significant boost for Buffalo's forward group, especially with Zach Benson (upper body) expected to be sidelined for at least three more games. Norris will join the first power-play unit and skate with Josh Doan and Noah Ostlund at even strength.

Washington Capitals goaltender Charlie Lindgren (lower body) was activated from Injured Reserve on Monday. The veteran netminder missed four games before the Olympic break due to a lower-body injury. Serving as Logan Thompson's backup, Lindgren has gone 8-6-3 in 17 starts this season, posting a 3.37 goals-against average, a .884 save percentage, and one shutout. Washington will resume the season on Wednesday night against the Philadelphia Flyers. The team also has a back-to-back on Friday and Saturday, so Lindgren is likely to start at least once this week.
