Leeds have confirmed that first-choice goalkeeper Andy Lonergan will be out for six weeks.Manager Simon Grayson confirmed that Lonergan fractured a finger in last week’s win at Doncaster RoversThe former Preston North End keeper has been sent for surgery and is unlikely to return until early December, robbing Grayson of one of United’s more influential players.Grayson said: “He’s going to be out for six weeks. He’s had an operation on the finger which he fractured on Friday night. It’s a blow for us and it’s a blow for the lad but I’ve got faith in Rachubka. He’s a keeper I can trust and who won’t let me down again.”Rachubka was a peripheral figure in a one-sided Championship game until his fumble in the third minute of injury-time handed Coventry a point and denied Leeds a third successive league win.Grayson said: “Paul’s frustrated but he’s a strong character. He’d had nothing to do all night but the game should have been over by half-time anyway with the opportunities we had.
