The breaks continue to go against the Maple Leafs where shot-block injuries are concerned.
Toronto Marlies assistant coach Rob Davison suffered a prolonged grand mal seizure prior to the club's game against the Texas Stars on Friday, but his condition has stabilized and he has been discharged from hospital, the team announced Saturday.
The Leafs said Rielly, who underwent a CT scan Monday afternoon, would be placed on injured reserve and reassessed after eight weeks.
Toronto has been without the services of forwards John Tavares, Mitch Marner, Zach Hyman, Alexander Kerfoot, Andreas Johnsson, Trevor Moore and Ilya Mikheyev, along with defencemen Travis Dermott and Jake Muzzin, at various points already this season.
The Marlies are scheduled to play a second game against Dallas' farm team Saturday night, part of a 3-on-3 weekend with a Sunday match in San Antonio. He's produced 15 points in 21 AHL contests with the Toronto Marlies this season and tallied 10 points in seven games with Sweden at the 2020 World Junior Championship, where he was named the tournament's best defenseman.
Marincin has also appeared in 65 career regular-season games with the Marlies, recording 25 points (five goals, 20 assists), while adding a goal and six assists in 20 career Calder Cup playoff games.
The team said at the time the 30-year-old was week to week, but he was placed on IR before Sunday's loss.
Marincin, a second-round pick (46th overall) by the Oilers in the 2010 National Hockey League draft, has 19 points in 129 games as a Leaf and was a member of coach Sheldon Keefe's 2018 Calder Cup champions.
