AFC Bournemouth were beaten 2-0 by Derby County after having goalkeeper Lee Camp sent off in the second half.
The recalled stopper was shown a red card in the 68th minute for handling Jamie Ward’s lob outside the area.
The ball ended up in the back of the net, but the goal was ruled out and substitute Darryl Flahavan appeared to touch Chris Martin’s free-kick on to the post moments later.
The Cherries were up against it for the final 20 minutes and eventually went behind thanks to Will Hughes’ well-taken finish.
It was harsh on Eddie Howe’s team, who had defended faultlessly and shown a great deal of resolve in the process, only to leave the iPro Stadium empty handed.
Martin added a second in the five minutes of additional time, converting a low cross in the six yard box.
The most significant team news from the visitors’ changing room was that Camp started against his former club.
On loan stopper Artur Boruc had been taken ill in the build up to kick-off, which meant Flahavan was brought into the squad.
Derby went into the match on an eight-game unbeaten run and certainly weren’t lacking in confidence, with Craig Bryson, Martin and Ward all going close early on.
But the Cherries, with lone striker Callum Wilson defending from the front, were proving tough to break down.
It was Wilson who had the away side’s first real opportunity, collecting Junior Stanislas’ clever through ball and aiming a mishit shot too close to goalkeeper Lee Grant.
Andrew Surman then saw his drive from the edge of the area go over the bar before Cyrus Christie burst forward and flashed a shot across the face of the goal.
However, the first half finished goalless and the second period was just as finely poised up until the 68th minute.
Rams forward Ward went one-on-one with Camp and lifted the ball into the back of the net. However, referee Scott Mathieson pulled play back and controversially disallowed the goal.
He instead opted to send off the former Derby number one and awarded a free-kick, which appeared to be saved acrobatically by Flahavan with his first touch.
Howe sacrificed Wilson and watched on as his side gave their all in the closing stages, only for Hughes to finally break their resistance in the 81st minute.
Yann Kermorgant was sent on for the final few minutes but the Cherries couldn't test Grant in a late rally.
Fourth official Ian Dudley indicated there would five minutes of added time, which was enough for Martin to make sure of all three points for Derby with a tap in.
