Heyward-Bey was belted by Mundy as he tried to haul in a Carson Palmer pass in the end zone early in the fourth quarter of Oakland's 34-31 win. There was no flag on the play, but Heyward-Bey was stabilized and carted off the field with a neck injury and concussion symptoms.
Heyward-Bey spent nearly 24 hours in an area hospital before being released Tuesday. Raiders coach Dennis Allen said Heyward-Bey was at team headquarters Wednesday, going through "concussion testing," according to CBSSports.com.
