Ajax said the following in a statement released on their website: 'Following a routine medical examination carried out by the Celtic medical department they discovered an underlying problem with his right foot. The clubs were therefore unable to conclude the deal based on the medical information available. The player will return to Ajax Cape Town for further evaluation.
'The injury has not hampered Coetzee to date having not missed out on any competitive action either for his club or the national team. Ajax Cape Town can confirm that they were not aware of any condition that would have potentially hampered a transfer to Celtic.
'While disappointed that the deal could not be completed at this point the club are fully committed to giving the player the care and attention required in order to make a full recovery. Stuart Baxter, the Bafana Bafana head coach has been informed as Rivaldo had been called up for the upcoming matches against Cape Verde.'
