The Maple Leafs selected Kokkonen in the third-round of the 2019 NHL Draft. The 21-year-old defenseman came to North America in 2021, playing 11 games with the Marlies, but has spent all of 2022 back in Finland. He had 15 points (1G / 14A) in 58 games with the Pelicans (Liiga).
Abruzzese was a fourth-round pick in 2019 and turns pro after two years at Harvard University. The 22-year-old centre was second on Harvard with 33 points (9G / 24A) in 28 games. He also notched one goa and three assists in four games with Team USA at the Olympics.

Liljegren has played in seven straight games, picking up six assists in that span, but will come out of the lineup on Saturday. Travis Dermott will be back in to replace him.
The Kraken are retaining 50 percent of Jarnkrok's remaining salary. Jarnkrok is a quality defensive-first forward, who could be a perfect fit on a line with Mikael Backlund and Blake Coleman.

Matthews cross-checked Dahlin in the head following a battle in front of the Sabres' net and he will miss Tuesday's game vs. Dallas and Thursday's game vs. Chicago. John Tavares and Alexander Kerfoot will likely take on larger roles with Matthews suspended.
