"We hung out a lot," Schenn said, "and I got to know him pretty well, so it was pretty easy to welcome him to the team. It makes things comfortable."
MacDonald debuted with the Flyers Wednesday. He and Schenn each had an assist and were plus-2. Schenn had five hits while MacDonald contributed three hits and three blocked shots.
MacDonald, acquired from the Islanders on Tuesday, said he was happy to join a team in the playoff race.
Temporarily serving as the Flyers' backup goalie because of Ray Emery's groin injury, Cal Heeter, 25, is soaking up the experience of being in the NHL.
"It would be nice if I got a chance to be in a game, but I understand the position they're at now," said Heeter, a former Ohio State star who had a 2.48 goals-against average and .916 save percentage with the AHL's Adirondack Phantoms this season. "They're trying to maintain a spot in the playoffs, and that may be more important than developing someone for the future. So I understand why I might not get a chance to play, but if I do get that chance, I'll be ready."
Steve Mason has started all four games since the Olympic break ended and has allowed 14 goals in that span.
Claude Giroux and Wayne Simmonds will trade their skates for sneaks Sunday. They will join the World All-Stars as they face the Harlem Globetrotters at the Wells Fargo Center at 5 p.m.
