Cardiff City striker Robbie Fowler will see a specialist in Germany next week over a recurring hip problem.
Fowler has felt discomfort in his hip over recent weeks
Fowler will be treated by renowned sport's injury surgeon Dr Hans-Wilhelm Muller Wolfhart, whose former patients include Michael Owen and Ronaldo.
"He's going to have an injection to see if that will settle it down," said Cardiff manager Dave Jones.
"He's had them before. It's another blow for him. There is nothing serious but it's best to do it now."
Fowler has struggled to reach peak fitness or top form since joining Cardiff on a free transfer over the summer.
His partnership with fellow new recruit Jimmy-Floyd Hasselbaink has yielded just seven league goals so far, prompting to calls for Jones to drop the misfiring pair.
Jones accepts the partnership has failed to meet expectations, but he is confident the experienced duo can rise above the constant scrutiny and criticism.
"They could have scored got a lot more, and they can do better in that department," Jones told BBC Wales Sport
"But they are working hard to get the partnership right, like everybody is.
"They always knew they would be criticised if the partnership didn't work and that's what happening at the moment.
"It won't be the first time in their careers it's happened to them. But they can sort it out - that's why they've been at the top of the tree."
For the first time since taking over at Ninian Park over two years, Jones is facing questions over his leadership.
We're far too good to be in the bottom three
Cardiff City defender Roger Johnson
Defeat against Charlton on Saturday could see the Bluebirds slip into the Championship relegation zone.
Jones was even criticised for not attending a reserve team match in midweek - which saw striker Steve MacLean's return to action from knee injury.
He says the scrutiny is natural given Cardiff's poor results and assured fans he was fully committed to the job.
"I actually arranged the reserve team fixture to give certain players 60 minutes playing time and all of a sudden I'm criticised because I didn't watch it," said Jones.
"I have watched the game - I've seen it twice on DVD and can tell you anything about it - but I already had prior arrangements so couldn't attend.
"It's just people being busy and they start to look and blame everything. If people want to see what my day entails, come and shadow me - they are quiet welcome."
Cardiff have gone four games without a Championship victory, but defender Roger Johnson feels a run of form is just around the corner.
"We're far too good to be in the bottom three and I'm sure the we're going to go on a run now of six, seven, eight games and get up the league where we should be."
