Wales defender Lewin Nyatanga has signed a new four-year contract at Derby - but could be loaned out by the Premier League newcomers this season.
Nyatanga lined up for Wales against the Czech Republic in June
He had one more year on his previous deal, but is now contracted until 2011.
Nyatanga, 18, started just five league games for the Rams last season, and was loaned out to Sunderland and Barnsley.
But with experienced defenders Andy Todd and Claude Davis joining this summer, Nyatanga could well find himself loaned out again this term.
However, he missed Tuesday's 2-0 win over Italian side FC Chiasso with a calf problem.
Dean Leacock and David Jones were on target for the Rams.
