Rob Hulse has become the latest Derby player to undergo end-of-season surgery.
The striker, the Rams leading scorer this campaign with 12 goals, has had a long-standing groin problem and had a minor operation last summer. Hulse is expected to be fit for pre-season training following this latest procedure.
"Rob has been carrying the injury for some time and we believe surgery will clear up the problem," said manager Nigel Clough.
Derby have been crippled by injuries this season and the problems have piled up again. Steve Davies had an ankle operation last week, Miles Addison underwent surgery on a foot problem and Stephen Pearson is due to have a knee operation on Thursday.
Davies is out for four to six weeks, Addison could be out for as long as a year and Pearson faces up to four months on the sidelines and will miss the start of next season.
