As expected, the Seahawks activated recently acquired wide receiver Deion Branch on Saturday and added him to the 53-man roster for the game Sunday against the Giants. To clear a roster spot, the Seahawks released defensive lineman Chris Cooper, who played well during the preseason but was stuck at the bottom of the depth chart. The NFL gave the Seahawks a two-week roster exemption for the former Super Bowl MVP, acquired Sept. 11 from the Patriots in a trade that ended Branch's 45-day contract holdout. Branch signed a $39 million, six-year contract with $13 million in guarantees two days later.
