Forst dislocated his shoulder on a hit from Jake McCabe in Tuesday's win over the Sabres. The Flyers have listed Frost as "out indefinitely" and said they will provide further details on his timeline in the near future. Connor Bunnaman is expected to draw into the Flyers lineup for Frost on Thursday.

With Joel Farabee sidelined with an illness, the Flyers are looking to Frost to inject some offence into their middle-6. Frost, who had seven points in 18 games with the Flyers earlier in the year, has tallied eight goals with 12 assists (20 points) in 30 AHL games this season.

Frost, who has picked No.27 overall in 2017, is one of the Flyers' top prospects and has registered 12 points (5G / 7A) in his first 16 career AHL games. Frost takes Carsen Twarynski's spot on the roster and should make his NHL debut in Florida on Tuesday.

Frost seemed like a front-runner to at start the season with the Flyers, but this injury all but guarantees that he will end up in the AHL next week. While this is bad news for Frost, it opens the door for fellow rookies German Rubtsov and Joel Farabee to make the opening night roster.
