Peterborough boss Darren Ferguson has said he may have to include 15-year-old striker Jaanai Gordan-Hutton in Saturday's squad to face Derby.
Posh could be without five first-team players for the visit of the Rams.
"He's at school today [Thursday] but there's a good chance he's going to be involved on Saturday," Ferguson told BBC Radio Cambridgeshire.
"He's a good player. He's strong. He's quick. He's one we definitely think has got a right chance."
Should he feature, Gordan-Hutton, who joined the Peterborough youth academy two years ago, would become Posh's second ever youngest debutant behind Matthew Etherington.
Chairman Darragh MacAnthony had already outlined his desire to see more youngsters come through the London Road ranks.
In October he said: "We've identified eight players over the next three seasons who could break into the first-team squad. That's an incredible number for any club to have."
Two 15-year-old footballers have made the headlines in the last fortnight.
Mason Bennett became Derby's youngest ever player when he started against Middlesbrough.
And Wycombe striker Jordan Ibe's strike in a loss to Sheffield Wednesday made him Wanderers' youngest ever goal-scorer.
