Charlie Austin's controversial late penalty sent West Brom back to the top of the Sky Bet Championship table as they won 1-0 at Preston on Monday night.
Needing a victory to make their way back above Leeds and to the summit, substitute Austin struck in the 90th minute after Preston goalkeeper Declan Rudd was deemed to have brought down Kyle Edwards in the box.
The result puts Albion two points clear of Leeds and seven clear of Fulham in third, while Preston are left in sixth after a first home defeat of the season at Deepdale.
West Brom win it late at Deepdale
West Brom dominated the first half in terms of possession against an injury-depleted Preston, but only created one real chance. It came from a free-kick after 32 minutes as Matty Phillips' smart delivery found Kyle Bartley at the back stick in space, but he sidefooted the ball wide.
Preston took until the 63rd minute to really create anything themselves, and it took a fine save from Sam Johnstone to tip Daniel Johnson's curling effort wide from the edge of the area.
That led to a flurry of opportunities for the home side, as Alan Browne saw a shot blocked just in front of the line by Nathan Ferguson, and then Jayden Stockley headed just over from the resulting corner.
Slaven Bilic made a host of attacking changes but the game appeared to be heading for a draw. At least until one of his substitutes, Edwards, raced in behind into the box and seemed to dangle a leg into the onrushing goalkeeper Rudd before going down. The referee pointed to the spot and Austin then rolled it home.
