The Ottawa Senators' top pick from the 2018 draft is leaving the college ranks.
The 18-year-old informed Boston University head coach Albie O'Connell of his plans, as reported earlier Saturday by ESPN's John Buccigross.
Tkachuk was mulling whether to return for a sophomore season at BU or to sign an NHL contract.
The Senators selected the winger fourth overall after he posted 31 points in 40 games with the Terriers.
He'll join Keith and his older brother, Matthew, as members of the Tkachuk family to sign NHL deals.
