Brennan is the Leafs’ top pick and will go No. 1 overall in the 2018 NHL Draft.
The Leafs traded for the rights to Brennan during the 2017 NHL Draft, a move that gave Brennan the ability to play in the NHL.
Brennan has spent time in the ECHL this season with the Tri-City Americans, and he’s expected to be the Leafs top pick.
The 23-year-old has played a career-high 21 games for Tri-Cities this season, scoring six goals and seven assists for 11 points.
Brennan was also named to the AHL All-Rookie Team.
Brennan played for the Tri Cities in 2017-18, helping the team reach the Calder Cup Playoffs.
The 6-foot-4, 210-pound winger is also considered one of the top prospects in the 2019 NHL Draft by NHL Central Scouting.
