Midfielder Kris Commons has handed Derby a much needed boost by declaring his fitness ahead of the weekend.
It was feared the 27-year-old would miss Saturday's game against Sheffield United at Pride Park due to injury.
The Scotland international was forced off a minute before half-time in the home draw against QPR 10 days ago.
But Commons, who had been plagued by hamstring trouble for much of last season, is back in the frame to face the Blades.
Rams boss Nigel Clough said: "Kris came off against QPR as a precaution because we didn't want his hamstring to go which would have meant six to eight weeks out.
"The international break has been ideal for him as he has had three or four days' rest and he is back training. It is a relief and now we hope he will have a good week's training.
"What happened is probably a result of him not having played much for two years and having had an intense period of five games in three weeks at the start of this season.
"He is still building his match fitness and match time to get to a stage where he can play a number of games in a handful of weeks and not feel it. He is not quite at that stage."
