Raiders safety Eric Cooper has been suspended the first four games of the season for violating the league’s policy on steroids. Cooper will be allowed to play though the preseason and participate in training camp, and his suspension will start on August 31st. The Raiders first four games are vs Detroit, at Denver, vs Cleveland and at Miami. He will be allowed to return after the teams bye week and his first game back will be on October 14th vs the Chargers. Cooper, who is a solid special teams player for Oakland, is the second player on the Raiders to have to sit for violating the teams substance abuse policy. Running back Dominic Rhodes will also be sitting four games as well. In other Raiders news, the team on Friday announced the signing of safety Eric Frampton to a contract. He is the 5th draft choice on the team to ink a deal. Frampton was Oakland’s second pick in the 5th round, and was an all-Pac 10 player last year at Washington State. The team also waived quarterback Josh Booty on Friday.
