ALBION's nine-match unbeaten run came to an end as they opened 2019 with a 2-1 defeat to Blackburn Rovers at Ewood Park.
Two goals in the space of five early second-half minutes did the damage as Charlie Mulgrew's whipped inswinging corner evaded everyone and found the net before Bradley Dack added a quickfire second for Rovers on the break.
Jay Rodriguez, cleared to play after Saturday's red card was rescinded, put Albion back in contention from the penalty spot, his 13th goal of the season.
But the Baggies, who saw substitute Jake Livermore sent off late on, were left to taste defeat for the first time since early November, ending a sequence of four successive away victories in the Sky Bet Championship.
