San Jose Sharks

Sharks: Roman Polak. The hulking defenseman will make his Sharks debut tonight paired with Brenden Dillon, who will be playing after missing the last six games due to an upper injury. Polak, 29, will add some size and toughness to the blue line, and provide some much-needed depth that had been lacking at that position since training camp.
Avalanche: Tyson Barrie. The defenseman is enjoying another strong offensive season with 40 points (10g, 30a) from the blue line. The 24-year-old has seven points (2g, 5a) in his last six games, and three helpers against San Jose in three games this season.
