Swayman will start in Friday's Game 6 at home versus the Sabres, Belle Fraser of the Bruins' official site reports.
Swayman kept the Bruins' season alive with an overtime win in Game 5 on Tuesday, stopping 25 of 26 shots. The 27-year-old will look to repeat that feat on home ice to force a Game 7, which would be in Buffalo on Sunday. Swayman has allowed 14 goals on 156 shots (.910 save percentage) over the first five games of the first-round series.
