Blackburn 2 West Brom 1: Albion fans disappointed at second-half display - WATCH
Albion fans were disappointed to start the New Year with a loss, but optimistic Darren Moore's men can still win promotion
As well as conceding two avoidable goals, including one straight from a corner, any chance of a comeback was dented by Jake Livermore's second red card of the season.
Charlie Mulgrew gave Tony Mowbray's side the lead in the 53rd minute with a delivery Sam Johnstone came for and missed, but the Baggies were too eager to get back level and allowed Bradley Dack to double the hosts' lead on the break five minutes later.
Jay Rodriguez pulled one back from the spot soon after to make it three goals in 10 crazy second-half minutes, but when Livermore hauled Lewis Travis to the floor in the 87th minute, any chance of extending the unbeaten run to 10 games disappeared.
