Murray was shown his second yellow card by referee Mike Dean??in the 69th minute after a tangle with Winston Reid, just six minutes after scoring Palace???s third goal of the afternoon in East London.
Pardew described Murray as having a ???mixed afternoon,??? as Palace claimed another three points in their battle to avoid relegation.
Pardew said of Murray: “He showed the qualities of a centre-forward with his movement.
???He could have had a hat-trick in the first half, we only had three or four chances and he had them all.
“The first goal was a great header from the corner, we got a bit of fortune from that, but his other goal was typical of him knowing where to be and he dispatched it.
“The sending-off was a little bit unlucky because I was literally subbing him for Shola (Ameobi) at that stage and he had to go for that in the box. I don’t think (Winston) Reid helped if I’m honest.
“But I think the ref would have sent him off anyway. So a mixed afternoon but I’m absolutely delighted with him because I think it’s a harsh sending-off and he’s not really meant to hurt anybody today. He was terrific.”
