OAKLAND -- Raiders quarterback Jason Campbell has been escorted off the field after suffering what appears to be a dislocated right shoulder on a scramble.
Campbell was replaced by Kyle Boller under center late in the second quarter.
Earlier, Campbell scrambled upfield and lost a fumble.
He immediately went into the locker room for testing.
UPDATE: The Raiders announced at the start of the third quarter that Campbells collarbone is being evaluated.
