Derby County first-team coach Paul Simpson has confirmed that forward Mason Bennett will be sidelined for up to eight weeks with a knee injury.
The 18-year-old suffered the problem last week during an Under-21 victory for the Rams against West Bromwich Albion.
Bennett scored the only goal of the game before he was stretchered off the pitch with the injury.
