'JJ' is out of the squad to face Spain in a friendly at Old Trafford on Wednesday with the injury he picked up in the Carling Cup loss at Arsenal last week. That ruled him out of Sunday's clash against Manchester United.
Martin reported this afternoon: "As everyone knows, JJ had a little stress fracture in his ankle, so he couldn't play for a couple of months and then he had a very good game when he returned against Southend in the FA Cup.
"His second game against Arsenal was okay but he had a knock on his ankle and that meant he was out again at the weekend.
"Hopefully he'll be back in the next couple of days because we need his mobility and aggression in there.
"The same applies for Teemu Tainio. He missed the weekend with a throat infection but again, he's improving and hopefully he will be back because he will also give us a bit of grit in there."
Martin Jol is hopeful Jermaine Jenas will only be out for another couple of days after missing out on England duty with an ankle knock.
