Paris Saint Germain striker Pierre-Alain Frau could face a spell on the sidelines with a foot injury.
The 26-year-old picked up a blow to his right foot in the Uefa Cup tie with Derry City and missed the weekend game against St Etienne.
Frau is still suffering discomfort in his foot and has undergone an MRI scan to discover the extent of the injury.
"It is still swollen and bruised. It doesn't hurt when I jog, however any contact with the ball is painful so I had an MRI scan," Frau said.
Doctors are now waiting on the results from the scan, which could rule Frau out for a couple of weeks.
Meanwhile, Jerome Rothen and Mario Yepes have rejected reports suggesting they could leave PSG.
Both players are unhappy at the lack of playing time under Guy Lacombe but insist they will not be departing the Parc des Princes in January.
Yepes and his agent Christophe Mongai met with PSG officials on Friday in the hope of clarifying the defender's situation.
"Mario's situation should not last," Mongai said. "I would be surprised if his circumstance changed."
Rothen has played just three times this season but no decision on his future will be made until the summer.
"In June 2007, he will just have one year remaining on his contract," Rothen's agent said.
"It can be important. Then will be time to extend or to leave."
