Forward Mitch Lewis is among a quartet of inclusions for Hawthorn as the club prepares to take on Richmond this Saturday afternoon at the MCG.
The 23-year-old, who started the year in impressive form, will return to the senior side after missing the last three games following a hamstring injury.
Youngster Sam Butler has also been confirmed to make his AFL debut this weekend.
Lewis and Butler will be joined in the senior line-up alongside the returning Chad Wingard, who is set to play his 200th game, and Conor Nash who comes back after being managed last week.
Tom Mitchell (managed) will miss the clash against the Tigers, while Connor Macdonald (managed), Josh Ward (omitted), Jackson Callow (omitted) and Liam Shiels (sub) are also outs.
Head of Football Rob McCartney said the four inclusions were a welcome addition as the side looks to bounce back following a disappointing result against Essendon last weekend.
"It's great to have Mitch back in our side. Before his injury he had demonstrated real growth in his game, showing a thirst for the aerial contest and an ability to impact the scoreboard," McCartney said.
"We look forward to seeing two of our emerging tall forwards it Mitch and Kosi playing together for the first time in 2022.
"Nashy returns after being managed last week, while Chad’s back after falling unwell ahead of what was set to be his 200th game.
"We’re excited to be able to celebrate this milestone with Chad this weekend, and his injection of experience and class will be important against Richmond.
"We’re also thrilled to welcome Sam for his first game. He’s shown some impressive form in the VFL and we’re confident he will take this opportunity with both hands.
"Tom has been unwell for the past week and as a result was unable to train for parts of this week.
"We were disappointed with our output against the Bombers, so the group is keen to rise to the challenge that the Tigers present."
The match will be played at the MCG at 1.45pm and will be broadcast on Fox Footy and Kayo.
