Karlsson underwent surgery to repair a small muscle tear in his left forearm on Monday and will miss at least 6-to-7 weeks. This is a terrible break for Karlsson, who was having a resurgent year, scoring eight goals with 18 assists (26 points) in 33 games. Ryan Merkley will likely remain with the Sharks with Karlsson out.
Karlsson will not play Saturday vs. the Lightning due to an upper-body injury. Radim Simek will replace him in the lineup and Ryan Merkley is expected to play an increased role.
Hayes, who recently had surgery on his adductor region, is expected to miss three weeks. Jackson Cates was called up from the AHL to take Hayes' spot on the roster.
Heinen has missed the last four games while n COVID-19 protocol but is expected to be back in the lineup on Thursday. While he's officially listed as a game-time decision, expect him to be back on a line with Jeff Carter and Evan Rodrigues.
Rust missed the last four games while in COVID-19 protocol but may play Monday in Vegas. Rust was one of the hottest players in the NHL before landing in protocol, scoring goals in four straight games, totalling 12 points (8G / 4A) in that span.
Malkin has not played this season but has been practicing regularly for a while. This is the first time that he's been listed as a game-time decision, which is a good sign that he'll be available in Anaheim. Malkin skated on the second line with Jeff Carter and Kasperi Kapanen and PP1 in Monday's practice session.
