Fulham boss Jol yet to deal in Grygera
Grygera is off contract and has resumed full-training and has played a part in some pre-season friendlies.
"Grygera's coming back from injury," said the Dutchman. "He's doing well but he's still not 100 per cent fit.
"We will have to wait until the end of this month or next month and then we will make a decision."
