QPR moved seven points clear at the top of the Championship after a 2-0 win at Coventry on Tuesday, while second placed Cardiff crashed 4-1 at Watford. Neil Warnock's side secured their first away victory in six games thanks to a second half own goal from Coventry goalkeeper Keiren Westwood and Tommy Smith's effort. In the 49th minute, QPR's on-loan Tottenham defender Kyle Walker burst down the right and smashed in a near post shot that hit Westwood's shoulder and cannoned into the net. The visitors netted again in the 61st minute when Adel Taarabt curled over a delightful cross which Smith glanced into the bottom corner. Cardiff's promotion hopes were dented by rampant Watford at Vicarage Road. Hornets striker David Graham missed an early penalty but he then bounced back to cancel out Peter Whittingham's opener. Goals from strike partner Marvin Sordell and midfielder John Eustace put the home side in control before Graham struck again. Jermaine Easter's first goal for Swansea clinched a 1-0 victory over Barnsley and ensured Brendan Rodgers' side ended a three-match winless run to move level on points with local rivals Cardiff. Easter, who completed an emergency deadline-day loan move from Milton Keynes Dons, scored in the 27th minute with a close-range finish from Nathan Dyer's cross. Leeds defender Andy O'Brien scored two own-goals as Portsmouth battled back to snatch a 3-3 draw at Elland Road. Simon Grayson's fourth placed side were firmly in control when Max Gradel struck his fifth goal in four matches in the seventh minute and Jonny Howson netted three minutes later. But Portsmouth hit back in the first half through David Nugent's superb strike. Bradley Johnson gave Leeds another two-goal cushion in the 62nd minute, but Leeds defender O'Brien deflected Richard Hughes' shot beyond his goalkeeper Kasper Schmeichel for his first own goal within 60 seconds to reduce the deficit. O'Brien then deflected Pompey substitute Nadir Ciftci's 93rd-minute cross into his own net to hand the visitors an unlikely point. Wes Hoolahan came off the bench to score a second-half hat-trick as Norwich beat Sheffield United 4-2 at Carrow Road. Simon Church's equaliser eight minutes from time helped Reading move into the play-off places as they drew 1-1 at Hull. Sven Goran Eriksson's Leicester were beaten 2-0 by 10-man Millwall, who had Alan Dunne sent off after first half goals from Steve Morison and Jason Puncheon. At the bottom of the table, Middlesbrough claimed a crucial 3-1 win at fellow strugglers Preston, while Scunthorpe beat Burnley 2-0 and Crystal Palace conceded a last minute equaliser in their 1-1 draw at Bristol City.
