PSV Eindhoven midfielder John de Jong has suffered yet another injury setback.
The 29-year-old has suffered almost two years of injury torment, with foot and knee problems hindering him since 2005.
De Jong had made good progress since the autumn and travelled to the club's training camp in Spain hopeful that he could challenge for a place in the team in the second half of the season.
However, he damaged a muscle in his left leg during a training session and has been told that he will not be fit for at least another six weeks.
De Jong last played for PSV on 20th March 2005.
