Leeds will not sign a goalkeeper on loan after Andy Lonergan was ruled out for six weeks with a fractured finger.
United's first-choice stopper suffered the injury in last Friday's 3-0 win at Doncaster and he has now undergone surgery. Paul Rachubka replaced Lonergan for Tuesday night's 1-1 draw against Coventry but he was at fault for the Sky Blues' injury-time equaliser.
However, Grayson said: "Lonergan is going to be out for six weeks. He's had an operation on his finger and it is a blow for the lad because he's been outstanding since he's been here. I've got a good, capable goalkeeper in Paul Rachubka who will stand in for him. I'm not going to be bringing anybody else in."
On Rachubka's mistake, Grayson added: "Goalkeeper is a position where you make a mistake and you get punished. He won't let me down again. It's just one of those things. He'll pick himself up. He'll be fine. I have no problems with him."
