First-round draft pick Mitch Marner was reassigned to the London Knights of the OHL by the Toronto Maple Leafs on Sunday.
The 18-year-old Marner was drafted fourth overall on June 26.
Toronto's current training camp roster includes a total of 23 forwards, 15 defencemen and four goaltenders.
One of those forwards is 33-year-old Brad Boyes, whom the Maple Leafs signed to a one-year contract on Sunday. He was originally invited to training camp with Toronto on a professional try-out.
Boyes appeared in 78 regular season games last season with the Florida Panthers, with 14 goals and 24 assists.
He has 203 goals and 278 assists in 762 career NHL games with the San Jose Sharks, Boston Bruins, St. Louis Blues, Buffalo Sabres, New York Islanders and Florida.
Boyes was originally selected by Toronto in the first round (24th overall) of the 2000 NHL Entry Draft.
Also cut from Toronto were veteran forwards Curtis Glencross and Devin Setoguchi, who were released from their professional try-out contracts.
Goaltender Rob Madore was reassigned to the Toronto Marlies of the AHL.
