Raiders put Christenson on IR Associated Press SAN DIEGO -- Tight end Brandon Christenson was placed on injured reserve on Tuesday by the Oakland Raiders, who signed veteran tight end Jeremy Brigham to their active roster in advance of the Super Bowl. The move likely won't affect the Raiders' lineup on Sunday, since rookies Doug Jolley and Marcus Williams have capably replaced Roland Williams, who's out for the season with torn knee ligaments. Brigham, a five-year veteran who was drafted by the Raiders in 1998, hasn't played all season while battling a knee injury. Christenson was waived in training camp and re-signed earlier in January.
