Derby County's new signing Nathan Tyson has been ruled out of his side's next five games with a groin injury.

The 29-year-old striker picked up the injury in Derby's 2-0 pre-season win against Aston Villa last Wednesday.

Manager Nigel Clough said: "People said it must have been a big boost beating Aston Villa but we'd have swapped the win to have Nathan available."

Tyson moved to Pride Park from East Midlands rivals Nottingham Forest on a free transfer in June.
