Derbyshire are sweating over the fitness of seam bowler Mark Footitt after he injured his back against Glamorgan on day one of their match.
The 26-year-old had bowled five balls in his fourth over when he suffered a pain in his lower back and side.
He was unable to continue and he will have a scan in the next 48 hours.
"We're hoping it's a slight injury and it'll go away but unfortunately it may be worse than that," head of cricket Karl Krikken told Radio Derby.
