Oakland Raiders head coach Dennis Allen gave little away when questioned on the injury quarterback Terrelle Pryor suffered against the Denver Broncos on Monday night.

Pryor left the field after a big hit in the fourth quarter of the 37-21 loss with a suspected concussion.

However, Allen didn't wish to speculate on the injury, instead stating that Pryor would simply be assessed on Tuesday to pinpoint the damage.

"We'll see with Terrelle," Allen told Raiders.com. "We'll evaluate him and see where we're at. He took a shot on that particular play where he got injured but that could happen to anybody.

"It's not just because Terrelle is a 'mobile' quarterback, that injury could've happened to a running back."

Rookie Pryor had put in another strong performance, throwing for 281 yards and a touchdown and rushing for a further 36 yards before his early departure.
