Trent Green's first practice with the Miami Dolphins was apparently Daunte Culpepper's finale in South Florida. Frustrated by the team's decision to let him only participate in individual drills, Culpepper walked off the practice field -- accompanied by a member of Miami's security staff -- about an hour into the start of a three-day minicamp and vowed that he'd block the Dolphins' plans to trade him. It was the latest entry in an up-and-down week for Culpepper. On Monday, he was told his surgically rebuilt right knee was strong enough to let him practice. Tuesday, he learned the Dolphins were trading with Kansas City for Green. Wednesday, the team told Culpepper they wanted to trade him, prompting his Thursday request for a release. "Any team that's interested in my services, just sit tight," Culpepper said. "I'm not going to agree to a trade."
