Gambrell was a second-round pick of the Sharks in 2016 and has turned into a decent bottom-6 option for them over the last two season. He has compiled 10 goals and 13 assists (23 points) in 99 games over that stretch and will likely centre the third or fourth line when 2021-22 starts.
Monahan has had an extremely disappointing season, scoring just 10 goals with 18 assists (28 points) in 50 games. Playing through a hip injury could help explain some of his inconsistencies throughout the season. The final four games are completely meaningless, so shutting him down now ensures he'll be ready for the start of the 2022 season.
Kuraly is one of 16 regulars who will not be in the Bruins lineup on Tuesday. The Bruins will need to recall multiple players from their taxi squad/AHL to fill out their lineup.
Kukan has been in the lineup for seven straight games but will sit Friday vs. the Red Wings. Scott Harrington will replace Kukan.
Fabbro has been out since April 6th but could be back in the lineup Wednesday in Columbus. Fabbro scored two goals and nine assists (11 points) in 38 games this season. He will likely replace Alexandre Carrier if he can play.
