Yeovil Town defender Jordan Clarke is facing a spell on the sidelines after straining his hamstring before the team's FA Cup victory over Accrington Stanley.
The 23-year-old suffered the injury during the warm-up before the Glovers booked their place in the third round with a 2-0 win on Tuesday.
Clarke is currently on loan at Huish Park from Coventry City until the start of 2015.
"We thought it wasn't going to be our day," manager Gary Johnson told the Western Gazette. "Jordan did a little burst out there on the pitch with his feet slipping in the mud and he's hurt his hamstring. Unfortunately he couldn't start."
Yeovil's victory over Accrington has set up a third-round clash at home to Manchester United.
