Boston defenseman Andrew Peeke is week-to-week with an upper-body injury and will not travel with the Bruins to Toronto, coach Jim Montgomery announced Tuesday.
Peeke appeared to be struck in the left hand by a puck before leaving the ice late in the second period of Game 2 on Monday night in Boston. He did not return.
The Maple Leafs won 3-2 to even up the Eastern Conference first-round series at one victory apiece. Game 3 will be on Wednesday night in Toronto.
Peeke, 26, contributed 10 points (one goal, nine assists) in 38 games while splitting the regular season between the Bruins and Columbus Blue Jackets.
He joined Boston in a four-team trade on March 8 that sent a 2027 third-round pick and defenseman Jakub Zboril to the Blue Jackets.
Peeke has recorded 44 points (10 goals, 34 assists) and 104 penalty minutes in 233 games since Columbus drafted him in the second round in 2016.
The Bruins recalled defenseman Mason Lohrei from Providence of the American Hockey League on Tuesday.
Lohrei, 23, posted 13 points (four goals, nine assists) in 41 games with Boston this season.
