"I know if he's had that he'll be incredibly stiff and it could restrict his movement, so I'm going (to have to see), but as everybody knows we need those top players to be firing on Thursday night and Jarrod is one of them."
He added: "Wolves has always felt a difficult place to come to.
"They've had some really good teams here over the years and they've got a big atmosphere here as well.
"So, things went for us today and we got a decision right at the end of the game which might have gone against us."
