- Maple Leafs prospect Roni Hirvonen suffered a concussion earlier today in a scrimmage game at Toronto’s development camp, notes David Alter of Sports Illustrated. Assistant GM Hayley Wickenheiser indicated that the 21-year-old will need some time to recover. Hirvonen was a second-round pick by Toronto back in 2020 (59th overall) and spent last season on loan to HIFK in Finland where he had 28 points in 57 games. He’s expected to play in North America this upcoming season with the AHL Marlies.
