Leyton Orient boss Russell Slade was critical of referee Dean Whitestone's penalty decision in their 1-1 draw at Preston.
Preston remembered their favourite son Sir Tom Finney, who died on Friday night, with an impeccably-observed minute's silence, black armbands and 'Finney' emblazoned on the back of every Preston shirt.
Mathieu Baudry scored the opener for the visitors at Deepdale just before the interval, but Joe Garner's penalty just after the hour-mark - after Baudry was deemed to have fouled Craig Davies - earned Preston a share of the spoils.
"We've taken the lead and Preston have equalised from a penalty situation, which I think was an excellent dive in my opinion," Slade said.
"I'm immensely unhappy with the decision and in the second half their keeper (Declan Rudd) has saved a shot outside of the penalty area - three or four yards outside - and that should've been a sending off.
"We're a threat from set-pieces which we really exploited - Baudry went close early on and then of course he put one away at the end of the first half.
"We were set up a lot better defensively and we really limited Preston to very few chances.
"Kevin Davies has had one glorious chance at the end, but apart from that they've not had a lot and I'm glad he didn't score because it wouldn't have been deserved.
"It was a difficult occasion. It was a big atmosphere and an emotional day all round.
"It was important that we got something out of the game and perhaps I'll look back on that as a decent point. But when I look at that penalty decision it's very disappointing."
