Conor Glass, James Cousins and Oliver Hanrahan have all signed contract extensions and will remain at the Hawks beyond the 2017 season.
Cousins and Glass have both signed two-year rookie extensions, while Hanrahan has been handed an additional year.
“We’re thrilled that each of these guys have extended their contracts,” Recruiting and List Manager Graham Wright told hawthornfc.com.au.
“Being on the rookie list, these boys are obviously still developing as footy players, but we’re really pleased with the steps they have taken since joining the club.”
Cousins joined Hawthorn with the 46th pick in last year's Rookie Draft, and has played three matches so far in his debut year this season.
“James has really impressed us this year. He’s great at winning the contested ball and thrives on the contest. He managed three solid AFL games this season, but unfortunately had to have shoulder surgery which has prematurely ended his season," Wright said.
He’s an exciting player, and we’re really looking forward to see what he can produce upon return.”
Glass made his debut a fortnight ago against Fremantle and played in his side's win over Sydney on Friday night, with Wright suggesting he's already adapted to the high level.
“Conor made his AFL debut just two weeks ago and has shown he is comfortable at the level. He is a great mark, displays great intent, and has shown great skills on either side of his body," Wright added.
"He will remain on Hawthorn’s Rookie list in 2018, with the promise of an elevation to Hawthorn’s senior list the following year."
Hanrahan is yet to make his debut for the Hawks, but has played an important role in Box Hill's VFL season.
“Despite a few niggling injuries throughout the season, Ollie has shown some really positive signs while playing for Box Hill this year," Wright said.
"He’s very creative with the football and has the ability to play both forward and on-ball. He is showing development with each game he plays."
