Fulham boss Martin Jol admits Pavel Pogrebnyak's ankle injury suffered in victory over Norwich City has given him a headache.

Jol revealed the Russia international has injured his ankle and will find out more information on its severity in the coming days.

"Pavel went off with something to do with his former injury," he said. "He twisted his ankle again so for us it is vital for us that he is back in the next couple of games.

"I think in the next one or two days we will find out more.

"He made a tackle on the touchline and he hurt himself."
