Cardinals tight end Todd Heap sprained his left thumb in Thursday's preseason opener against the Raiders. Heap had two catches for 23 yards before heading into the locker room for X-rays. The tests came back negative, and he said he could have returned to the game if it was the regular season. Heap may skip some practices, but there's not much real concern here.

Good choice on not coming back in. No sense in risking further injury in a preseason game. Especially the first game.
