Queens Park Rangers' winless run was extended to eight games to pile on the pressure on boss Gareth Ainsworth as his luckless Hoops lost to two second-half goals by West Bromwich Albion.
After a dreadful first half, the game all hinged on a 58th-minute incident in which Albion were awarded a controversial penalty before Jimmy Dunne was sent off for arguing about it.
After Grady Diangana was adjudged to have been brought down by Kenneth Paal, several QPR players showed dissent - and referee James Bell issued centre-back Dunne with a second yellow card to earn the Rangers defender his early exit.
