Under-fire Blackburn boss Steve Kean believes Newcastle's crucial third goal in their 3-1 win over his team should not have stood.
Kean claims Rovers defender Scott Dann would have cleared Demba Ba's header but was fouled by home striker Leon Best as the ball went over the line.
His team went 2-0 down in the space of three first-half minutes before Junior Hoilett halved the deficit with a thumping strike.
Martin Olsson hit the Newcastle bar shortly before Ba's third but was later sent off for two yellow cards.
The Scot said: "We feel a bit aggrieved because we were trying to get the equaliser, we hit the bar, then we feel when the ball came in Scott Dann is just about to clear it off the line and Leon Best bundles him over.
"In effect it's a triple whammy - we concede a goal, Scott's injured and then Martin Olsson is protesting to the referee and gets himself booked.
"Then eventually he gets another and gets sent off.
"So that goal was the turning point in the game. We feel it was a clear foul.
"I've looked at it again and I'm struggling to find out why it isn't a free-kick."
Kean reckons his side were holding their own against the home side before the controversial moment and believes it swung the game back in Newcastle's favour.
He added: "We got back in it but even before that we didn't think there was very much in the game.
"We were chipping away, we were having our own counter-attacks and our own chances. Then we got ourselves back in the game.
"Then the whole momentum swung on that moment.
"Some of our momentum from the win over Arsenal has been lost because we don't get any points from this game. But I think we did well in spells."
