Goalie Brian Boucher could miss as much as a month with a sprained MCL of his left knee, GM Paul Holmgren said after Tuesday's practice in Voorhees. Boucher injured both knees in Monday's 4-0 win in Boston, but the left knee is is worse shape, Holmgren said.
Holmgren said center Claude Giroux, who injured his shoulder when boarded late in the second period, would play Wednesday, when the host Flyers try to even the series.
Boston's 3-0 series lead has dwindled to 3-2.
The Flyers are trying to become the third team in NHL history to win a series after losing the first three games.
