The Raiders brought back Doug Gabriel on Wednesday three months after trading him to New England as insurance for Randy Moss' ankle injury. Gabriel had been slated to start in Oakland before being traded to New England for a fifth-round pick just before the beginning of the season. He was cut this week by the Patriots and claimed by the Raiders because Moss is questionable for Sunday's game against St. Louis. Gabriel is expected to join the Raiders on Thursday and could be used Sunday against the Rams.
