Derby are hoping to get to the bottom of striker Chris Porter's ongoing hip problems.
The 26-year-old has undergone a series of scans on the troublesome injury that has seen him in and out of the side since joining from Motherwell back in January 2009.
Porter has not featured for the first team since the Championship game at Coventry on 21st August and he has made just one start, in the Carling Cup defeat at Crewe.
Now Rams boss Nigel Clough is determined to get to the root of the problem in the hope Porter can play some part in the club's push for promotion.
"This week he has had a bone scan and he is having a gait analysis," Clough told the Derby Telegraph.
"We will have a get-together in the next couple of days with the doctors and the specialists to try to ascertain what the next step is.
"We are sending Chris to see every possible specialist we can and looking at different parts of the hip."
