Rask removed for 'some maintenance,' expected to be ready for Game 6
"There was some maintenance that needed to be done. He wasn't 100%. He wasn't himself," Bruins head coach Bruce Cassidy said postgame, according to ESPN's Greg Wyshynski. "He could have been back in. We made the decision not to put him back in."
Cassidy added that he expects Rask to be ready to go for Game 6.
Rask was replaced by Jeremy Swayman to start the third period after allowing four goals on 16 shots, including a trio of second-period markers. The Islanders were also able to score three power-play goals on the former Vezina Trophy winner.
Swayman didn't see much action during the third, as he allowed one goal on only three shots faced. Boston managed to close the gap but still fell 5-4, and Swayman was credited with the loss. The Islanders now have a 3-2 series lead and will look to finish the series on home ice Wednesday.
It marked the NHL playoff debut for the 22-year-old Swayman, who appeared in 10 games as a rookie for the Bruins this season. He was 7-3 with a 1.50 goals-against average and .945 save percentage during the regular season.
