White, a forward taken by the Ottawa Senators in the first round (No. 21) in the 2015 NHL Draft, had six points (two goals, four assists) in 21 games in 2017-18, his first extensive NHL stint. He was recalled from Belleville of the American Hockey League on Jan. 6, 2018, and scored his first goal exactly one month later in a 5-3 victory against the New Jersey Devils.
He was scoreless in two games for the Senators late in the 2016-17 season after signing with Ottawa following two seasons at Boston College. He made his NHL debut against the Detroit Red Wings on April 3, 2017. White also played in one game in the Stanley Cup Playoffs -- Game 6 of the Eastern Conference Final against the Pittsburgh Penguins.
