MacDonald is considered day-to-day after getting knocked out of Sunday’s game in Pittsburgh on a hit by the Penguins’ Tom Kunhackl.
It’s expected that Evgeny Medvedev will take MacDonald’s spot in the lineup against the Red Wings. Medvedev hasn’t played since March 12, more than three weeks ago.
The Flyers have four games left in the regular season, all in a five-day span — at Detroit Wednesday, home to Toronto Thursday, home to Pittsburgh Saturday, and at the Islanders Sunday.
According to Sports Club Stats, they have a 78.7 percent chance of making the playoffs.
