The Cherries moved down to tenth in the Sky Bet Championship table following a 3-1 defeat against Blackburn Rovers.
Rovers claimed all three points at the Goldsands Stadium with some clinical finishing in the first half.
Jordan Rhodes and Leon Best put the visitors ahead from close range before Scotland international Rhodes added a third from the penalty spot.
The Cherries, who had an early Tokelo Rantie strike disallowed and hit the post through Marc Pugh, pulled one back when Ryan Fraser side-footed the ball past the on rushing Jake Kean 15 minutes from time.
Eddie Howe’s team also played the final 35 minutes with ten men after substitute Richard Hughes was sent off, which means the midfielder will miss the midweek fixture against Leeds United.
The Cherries started well and had the ball in the back of the net after just five minutes, but Rantie’s close range strike was disallowed when he was flagged offside.
However, Rhodes opened the scoring shortly afterwards, guiding a low cross past Ryan Allsop with a well taken diving header.
There were chances at either end following Rhodes’ goal as Rovers’ record signing had a free-kick pushed away and Kean saved Steve Cook’s header.
But Best then made it two as he tapped in Corry Evans’ low cross inside the six yard box in the 24th minute.
Rantie’s pace and persistent was causing the visitors problems, but the Cherries couldn’t put together any sustained pressure in the final stages of the second half.
Rhodes, though, scored his second goal and Rovers’ third of the afternoon from the penalty sport after Tommy Elphick brought down Josh King just inside the box.
Howe sent on Fraser for Brett Pitman at the interval as the Cherries switched to 4-4-2, but he was forced to reshuffle his team when Hughes was sent off in the 51st minute.
The midfielder picked up his second yellow card in the space of a few minutes as he brought down Evans on the half way line with a late challenge.
Pugh then hit the post as the Cherries looked for a way back into the game, which eventually came through Fraser.
The winger raced on to a through ball and calmly poked the ball home for first career goal.
Meanwhile, Mohamed Coulibaly made his return as a late substitute, replacing Eunan O'Kane in the final ten minutes.
