Bournemouth added to the pressure on West Brom manager Alan Pardew with a late comeback to win 2-1 at the Vitality Stadium.
Jay Rodriguez put West Brom ahead early in the second half, firing home after Salomon Rondon knocked Kieran Gibbs' cross down into his path.
But in the final quarter hour, with Pardew beginning to dream of a first win in eight games, Albion lost captain Jonny Evans to injury and Jordon Ibe almost immediately curled a superb 25-yard shot into the corner of the net.
And worse was to follow for the visitors as Junior Stanislas produced an equally impressive strike from a free-kick a minute from time to inflict a seventh straight defeat on Pardew's rock-bottom side.
