With the clock ticking towards a goalless draw and a welcome clean sheet, a hopeful punt forward was won in the air by Pierre Yves Andre before Youri Djorkaeff was felled by Gary Doherty.
"We started off quite well, but didn't really get going in the second half and had to defend a lot of long balls," said the central defender.
"It was testing and I was disappointed that the lad managed to beat me in the air for the flick on that they got the penalty from."
The denial of a first shut out since the January victory at Aston Villa was a particularly bitter pill to swallow for the defensive unit that did well to repel a determined second half onslaught from the home side.
"As a defender you've got to set your stall out and go for a clean sheet. It would have been nice to have kept one, even though we didn't play the way that we can.
"To come away having lost at the end is really disappointing. To lose like that is a big knock back and we've got to try and lift ourselves for the next few games."
Ledley King admitted his disappointment at losing the headed challenge that led to Bolton's penalty winner on Monday evening.
