Carter Hart did not start Saturday’s game because of a lower-body injury. He has been replaced by Alex Lyon.

Hart had been scheduled to be in net for the Capitals game with Brian Elliott getting the start against the Islanders on Sunday.

Lyon’s only appearance this season was in relief of Elliott in a 6-1 loss at Buffalo on March 31. He started two games last season and has made 10 starts in his NHL career (5-4-1, .893 save pct.).

Lyon led the team onto the ice for pregame warmups, a traditional honor held for the starter. Elliott is backing up.

It’s unclear when Hart was injured or the nature of his problem, He participated in Friday’s optional practice in Voorhees, N.J.

It has been a rocky season for Hart (9-11-5). His save percentage has dipped from .914 last year to .877 and his goals against average has risen from a steady 2.42 to an unsightly 3.67.

Hart snapped a personal seven-game losing streak when he allowed just one goal and made 31 saves against Pittsburgh on Thursday. It was his best game in more than a month.

After Sunday’s game, the Flyers will be off for three days before consecutive games in New York against the Rangers Thursday and Friday.
