Puustinen was a seventh-round pick in 2019 and has scored 13 goals with 14 assists (27 points) in 40 AHL games this season. The 22-year-old is in his first season in North America and could make his NHL debut on Tuesday after Evgeni Malkin was moved to the COVID-19 protocol list on Monday.
Felhaber was an undrafted free agent out of Ottawa (OHL), who has scored two goals in 14 games with Texas (AHL) this season. He will report to Syracuse (AHL).
With Kiviranta out, Riley Damiani was recalled from Texas (AHL) and will draw into the lineup on the fourth line. Kiviranta is considered day-to-day.
Manson suffered an upper-body injury in Ottawa on Saturday and will not be available for Monday's game in Detroit. Josh Mahura will draw into the lineup to replace him.
Merkley will replace Mario Ferraro, who was hit in the face by a puck on Saturday. Merkley, who has one goal and one assist in 14 games, will skate with Marc-Edouard Vlasic on the second pairing and should quarterback the second power-play unit.
It's unclear if MacKinnon will be ready for the All-Star game but he'll miss Colorado's last three games before the break. Mikko Rantanen will move to centre with MacKinnon out.
Manson has missed the last four games while in COVID-19 protocol but will return to the lineup on Thursday. It's unclear who Manson will replace on the blueline or if the Ducks will go with seven defensemen. He has scored three goals with three assists in 41 games this season.
Blackwood served as the backup on Monday but the Devils said that he was dealing with something and wasn't 100 percent. Moving him to IR opens up a roster spot to recall Akira Schmid from Utica (AHL) to serve as the Devils' backup behind Jon Gillies.
Entering COVID-19 protocol means that Manson will miss at least the next two games. He'll most likely be back in the Ducks' lineup next Monday in Boston.
Nichushkin will not be available for Monday's game vs. the Wild and will likely miss their first three games to start the week. Expect J.T. Compher to move into the top-6 with Nichushkin out.
