In the game on February 14 in Winnipeg, San Jose Sharks defenseman Erik Karlsson suffered a broken thumb on his left hand, which will require surgery.

The injury will keep him out for the remainder of the 2019-20 season but he will be recovered well in advance of the team's 2020 training camp in September.

Additionally, the team announced that they have recalled defenseman Jake Middleton from the San Jose Barracuda, the team's top development affiliate in the American Hockey League.
