Washington Capitals defenseman Matt Roy (lower body) is day-to-day, Sammi Silber of The Hockey News reports. Roy was hurt over the weekend against Tampa Bay and didn't practice on Monday. He's in jeopardy of missing his first game of the season on Wednesday versus Philadelphia. Roy's absence would open the door for Dylan McIlrath to make his season debut. Additionally, Timothy Liljegren and Vincent Desharnais are likely to see more ice time, though neither player is an attractive fantasy target.

Chicago Blackhawks winger Andrew Mangiapane (lower body) is week-to-week, head coach Jeff Blashill told reporters on Monday. The 30-year-old suffered a lower-body injury in last week's season opener against Chicago and has already sat out two games. Blashill's update suggests Mangiapane will sit out several more games. It's a bad blow for a player who has endured disappointing campaigns in recent years. In 2025-26, Mangiapane amassed only 16 points (eight goals, eight assists) in 62 games. Even when Mangiapane returns to the Blackhawks' lineup, he isn't expected to play a major role.

Tampa Bay Lightning defenseman Emil Lilleberg (undisclosed) won't be in action for approximately one week, Eduardo A. Encina of the Tampa Bay Times reports. He suffered an undisclosed injury in Saturday's win over Washington and will exit the lineup on Monday against Philadelphia. Lilleberg's absence will allow Maxwell Crozier to make his season debut as the Lightning continue to roll with seven defensemen. While Crozier has shown some potential, he isn't expected to make a fantasy impact in a third-pairing role.

Philadelphia Flyers defenseman Rasmus Ristolainen (undisclosed) will miss Monday's contest against the Tampa Bay Lightning, Jackie Spiegel of The Philadelphia Inquirer reports. Ristolainen didn't join his teammates for pregame warmups after being considered a game-time decision. He sustained an undisclosed injury on Saturday against Carolina. With Ristolainen out, Simon Benoit will be back in the lineup. After playing in the first two games of the season, Benoit was scratched for Saturday's action. Benoit has no fantasy value and should be ignored by managers. Travis Sanheim, Cam York, and Jamie Drysdale will carry the Flyers' defense.
