Preston boss Darren Ferguson conceded his side had gone down to a better team after Nottingham Forest's 2-1 win condemned North End to a fifth defeat in six games.
Ferguson's men lost 4-3 at Burnley on Saturday, despite leading 3-1 with six minutes remaining, and Ferguson's angry reaction to referee Kevin Friend at Turf Moor led to him being charged by the Football Association with improper conduct.
A superb double from 21-year-old Forest midfielder Lewis McGugan cancelled out Jon Parkin's 42nd minute opener, with former Peterborough manager Ferguson admitting he could have few complaints.
"We never really got going, passing-wise and energy-wise," he said. "Forest were the better team. They passed the ball better and seemed to have more energy.
"At half-time I thought we would go on and win it, but unfortunately there really wasn't any improvement in the performance in the second half.
"The real disappointment was letting a lead slip again."
