Jeremy Swayman will not play in Thursday's game against the Ottawa Senators due to an upper-body injury suffered the day before.

Trent Frederic will return to the Bruins lineup after missing two games with an illness. Sacco said there could be other game-time lineup changes. After Wednesday’s loss at New Jersey, Sacco said Swayman was “dealing with something minor” after he replaced him with Joonas Korpisalo in the third period.

Swayman departed the contest at the end of the second period and was replaced by Joonas Korpisalo, who made five saves on six shots. Swayman has found himself on the losing end in four of his last six starts, a span in which he's gone 2-3-1 with a 3.45 GAA and a .913 save percentage.

Korpisalo appeared in relief and stopped five of six shots in Wednesday's 5-1 loss to New Jersey. Korpisalo entered the ice in the third period after Jeremy Swayman allowed four goals on 29 shots faced before being pulled.

Jeremy Swayman returned to Boston practice on Friday and Michael DiPietro was back in Providence which likely signals a return toward goalie normalcy within the Bruins organization.

The Bruins hope to keep their own point streak going while keeping the Devils on the skids on Wednesday. Jeremy Swayman gets the start.
