The Panthers (33-33-11, 77 points) were mathematically eliminated from the postseason after a 6-2 loss at the hands of the Montreal Canadiens on Thursday night.
Even though the Bruins will be facing a team outside the playoff picture, Cassidy and his bunch will be weary of a young Florida team one year removed from a 103-point season in which they captured the Atlantic Division title.
Aleksander Barkov, the Finnish native whom the Panthers selected second overall in the 2013 NHL Entry Draft, missed Thursday's game against Montreal with an upper-body injury. His status for Saturday's game is yet to be determined.
Barkov (21 goals and 31 assists) and Vincent Trocheck (22 goals and 31 assists) are spearheading the youth movement in Florida as the team's top scorers this season. Trocheck, 23, and Barkov, 21, have given the Sunshine State plenty to be excited about for years to come.
Jaromir Jagr wouldn't be considered a part of the youth movement. At 45 years of age, however, the future Hall of Famer has plenty of spring in his step, having notched 15 goals and 27 assists in his 23rd NHL season.
The Panthers will also likely be without defenseman Aaron Ekblad, the No. 1 overall selection in the 2014 NHL Entry Draft. Ekblad, one of the league's young stars on the back-end, is still recovering from the effects of a concussion he suffered March 11 against Tampa Bay.
The Panthers are hoping to have Roberto Luongo in net against the Bruins on Saturday. Luongo has been out since March 2 with a core injury he suffered against the Philadelphia Flyers.
James Reimer (16-15-5, 2.60 GAA, .917 save percentage) and Luongo (17-15-6, 2.68 GAA, .915 save percentage) have each played 40 games this season while posting almost identical stat lines.
Florida ranks 23rd in the NHL in goals for (2.52 goals per game) and 20th in the NHL in goals allowed (2.81 goals per game).
