If Keith Traylor's career is over, it ended on a sour note. The Dolphins banished the starting defensive tackle for the season's final game, the result of an argument he had with teammates on the flight back from New England last week. According to two sources, the fight was with offensive linemen Rex Hadnot and Vernon Carey. Traylor, 38, did not practice last week, and the team listed him on its injury report with an ankle ailment. Cam Cameron met with Traylor on Monday,; they argued; and the coach kicked him off the team, one of the sources said. Teammates pleaded his case, and the team invited him to return but with a fine. Traylor refused.
