Martone was drafted by the Flyers sixth overall last month.
In November, the NCAA Division I Council voted to amend its rules, permitting players who have skated in the CHL to participate in college hockey. Martone will join the Michigan State Spartans, who had a 26-7-4 record this past season. The team plays out of Munn Ice Arena in East Lansing, Mi.
He spent most of his OHL career with the Mississauga/Brampton Steelheads and had a brief stint with the Sarnia Sting, playing 29 games during the 2022-23 season.
He finished this season with 37 goals and 61 assists in 57 games while captaining the Steelheads. He also captained Team Canada to a gold medal at the IIHF U18 World Championship last year in Finland.
The Peterborough forward was a member of the Petes U15 AAA team, scoring six goals and 15 assists in 36 games.
Porter is the son of his father and former NHL player Mike Martone. The latter was known for scoring the game-winning overtime goal in the 1996 OHL Championship against the Guelph Storm.
