DENVER -- Raiders linebacker Sio Moore was with the team when it arrived in Denver after being involved in an auto accident Saturday morning and being diagnosed with a concussion.
Moore was added to the injury report and listed ``questionable'' to face the Broncos Monday night at Sports Authority Field.
On his Twitter account, Moore said, ``Talk about a scary morning man. Just thank God I'm safe and made it safely to CO.''
Then he tweeted: ``100 percent I'll be in black with my squad.''
The Raiders were disclosing no details regarding the accident.
Moore must go through the NFL concussion protocol, passing a battery of mental tests, to be cleared for action Monday night.
