Before the game, Cassidy provided updates on Brandon Carlo and Riley Nash, both of whom left Saturday's win over Florida with injuries.
Nash needed 40-plus stitches to his ear/head after being struck by a puck and did not travel with the team. The veteran center could meet the team in Florida once the discomfort from the stitches dies down and he is able to comfortable wear a helmet.
Carlo, who was ushered from the ice on a stretcher after an awkward fall by the Zamboni entrance in the third period, also did not travel for the trip. Cassidy said the blue liner had a lot of swelling in his leg, meaning a final determination on the extent of the injury has not yet been made.
"We should know more very soon…looking at the video, it's probably not going to be good news," said Cassidy. "But I don't have definitive answers today. If he does [miss the playoffs, it [stinks] for a guy that's played almost every regular season game, been healthy through two regular seasons."
Last season, Carlo suffered a concussion in the final regular season contest and missed all of Boston's six-game playoff series with Ottawa. The 21-year-old missed only one game this season, as a healthy scratch.
"I think the whole group felt bad for him, seeing him go off the ice on a stretcher," said Cassidy. "Let's face it, you go off the ice on a stretcher, it's probably not good news. But we're holding out hope it's not as bad as it looked."
Charlie McAvoy, out since March 3 with a sprained MCL, is with the team and skated on his own prior to the game. He could return on Tuesday in Tampa.
