Two days after handing out a written statement in which he said he was considering filing a grievance against the Dolphins for barring him from participating in team drills, estranged Dolphins quarterback Daunte Culpepper has decided to do so. Although NFL Players Association attorney Richard Berthelsen was traveling Monday and unable to return phone messages, he did send an e-mail to NFLPA director of communications Carl Francis in which he confirmed that a grievance will be filed "sometime soon" against the Dolphins in an effort to force them to release Culpepper.
