Cardiff manager Dave Jones: "It was a stonewall penalty when the Newcastle player handled the ball, but if you make a defensive mistake like we did in the first half, you have to suffer the consequences.
"We had good positions to get in on goal and dominated the game for long periods, but at this level, in a tight match, you do expect the officials to get it right.
"We knew it was going to be a tough game both on and off the pitch, but we had to break 10 men down and we have to be wiser.
"I have no complaints about losing the match, but when you lose you always feel hard done by, especially when the referee has to be brave under those conditions.
"Newcastle stopped our flow and Alan Smith was probably unlucky to be sent off, but they have Premier League players and know exactly how to put their bodies on the line when necessary."
