Derby forwards Kris Commons and Steve Davies could be in line for contract extensions - if they can prove their fitness.
Both players were plagued by injury last season and are about to enter the final year of their current deals. Hamstring problems restricted Commons to 24 appearances and only 14 starts.
Davies was also hampered by his hamstrings and required ankle surgery towards the end of the campaign. He made 22 appearances in all competitions and just nine starts.
"In Kris Commons and Steven Davies we have, in the manager's opinion, two of the most talented players in the Championship. The challenge with them has been fitness and continues to be," Rams chief executive Tom Glick told the Derby Telegraph.
"Both are coming back in early this summer, which shows a great attitude. It shows their personal commitment towards having a great season for themselves and for Derby County. You can't ask for any more than that."
He added: "I'm thrilled to see it, particularly as they have done it on their own initiative. It bodes well for the new season.
"Our bias is towards extending the contracts of both players. However, we and the players want to make sure they have a good pre-season and good start to the season."
