According to Steve McNair?s agent Bus Cook, the NFL Players Association has intentions to file a grievance against the Tennessee Titans on behalf of the quarterback, who was prohibited last week from working out at the team?s training facility until his contract situation can be resolved. ?We talked with them last week about it, and they either filed it on Friday or are planning to file it Monday morning,? Cook said. ?They do a good job of representing the players in matters like this.?
