Highlights: Blackburn Rovers 0-1 Millwall
Blackburn Rovers manager Michael Appleton said his players were "devastated" after falling 1-0 to Millwall in the FA Cup.
The Lions secured a spot in the semi-finals of the competition when Danny Shittu connected with a Chris Taylor corner to score the only goal of the game and send the visiting fans into rapture.
Millwall now move on to meet Premier League side Wigan Athletic.
However, Appleton painted a grim picture of the home dressing room after the game.
"It is very disappointing as you could probably imagine the players are devastated in the dressing room," Appleton told Radio Rovers.
"The lads gave me everything, they worked their socks off. We huffed, we puffed, we had a couple of chances in the second half, a goal-line clearance, but it just wasn't to be."
The biggest talking point after the game was the debatable decision to award the corner which led to Shittu's decisive goal.
But despite the protests, Appleton was more concerned as his side's inability to deal with the set-piece.
"I think (the decision to award the corner) is debatable but ultimately whether it is given or not, you've got to make sure that you deal with it and you can argue about it later," Appleton said.
"I think it is disappointing the way we conceded the goal. To lose out on a set play in that manner was disappointing."
Appleton said his side must now forget about its amazing Cup run, which included knocking out Premier League heavyweight Arsenal, and re-focus its attention on the Championship.
"Wembley was the prize at the end of the game today, we knew what it was success or failure," he said. "We've failed on this attempt but there are ten games left this season, plenty of football and hopefully we can finish on a little bit of a high.
"There's no point grumbling about it. It is devastating for the players and everyone concerned, we just have to move on quickly."
