The Hungarian has failed to make an appearance for the first team since signing for the Whites in 2011 following a successful trial.
"He's another player we have to make a decision on," said Jol to the Fulham Chronicle.
"He's never played for the first team but was a great guy to have here. He's a good keeper, went on loan and was man of the match four times in eight games, although it was a lower level.
"We have to sit down with him and tell him what we'll do."
