Huddersfield withstood the second-half dismissal of Christopher Schindler to claim all three points and extend West Brom's torrid run.
A spectacular Rajiv van La Parra strike secured a slender 1-0 victory for 10-man Huddersfield Town over an insipid West Brom at the John Smith's Stadium.
The result maintains the Terriers' impressive home form this season, which has seen them emerge victorious in three of their six games, while Tony Pulis' side remain without a win in the Premier League since August 19.
A poor first half was lit up in the 44th minute when Van La Parra curled home magnificently from 30 yards past Ben Foster.
