Darris Heyward-Bey was knocked unconscious by Ryan Mundy during the Oakland Raiders' Week 3 win over the Steelers.

“I don’t remember any of it, so I wouldn’t be able to tell you,” Heyward-Bey said. “The first thing I remember is being carted off the field.”

Heyward-Bey said Mundy texted him soon after the incident.

“I told him, ‘Hey, it’s football,’ ” Heyward-Bey said.
