Lee Buchanan is likely to miss the start of Derby County's Championship campaign.
The 20-year-old left back has a thigh injury that looks set to rule him out of the opening fixture against Huddersfield Town at Pride Park Stadium on Saturday.
Manager Wayne Rooney confirmed the news following Derby's 2-0 victory over Notts County in their final friendly of pre-season.
England youth international Buchanan missed the game against National League opposition at Meadow Lane on Sunday.
"He went off at half time against Real Betis," Rooney said.
"He felt the top of his thigh and he will be touch and go for Saturday.
"It is looking unlikely he will be ready, but we will give him this week and see how he is.
"If not Saturday, he will be available the following week."
This points to Craig Forsyth playing left-back against Huddersfield.
Buchanan has been the subject of transfer talk this summer with rivals Nottingham Forest having a bid for the England Under-21 international rejected.
