Oakland Raiders quarterback Terrelle Pryor did not practise on Wednesday, after a suspected concussion injury sustained in week three.

Pryor took a big hit during the defeat to the Denver Broncos on Monday night, and although he has been cleared for team meetings, he is not ready to practise fully.

According to NFL.com, Pryor was nowhere to be seen at the training camp, with backup quarterback Matt Flynn taking first-team snaps.
