Newcastle United defender Davide Santon has been denied a debut against Aston Villa due to a knee injury.
Pardew has revealed Santon was sent for a scan after hurting his knee on the training ground this morning and will not travel to the midlands.
He said: "Unfortunately, David has hurt his knee this morning. He's going for a scan today. That's not good news for us.
"He's having a scan on what looks like a possible cartilage [injury]. His knee looked a little bit unhealthy after training today.
"It's an injury he's had previously, so I think it's very wise that the doctor and his team have had him scanned today to make sure.
"I'm not actually sure of the mechanics of it [how it occurred]. It's very important he has a good start at this football club, so we want to make sure he's 100 per cent."
