Dick Vermeil will retire after the season as head coach of the Kansas City Chiefs, one of his players told The Associated Press on Saturday night. The player, who asked that his name not be used until after the announcement was official, said he was present when Vermeil broke the news during a team meeting earlier in the day. The Kansas City Star first reported that Vermeil was leaving, quoting team official Lynn Stiles. The 69-year-old Vermeil, the NFL's oldest head coach, could end his career on Sunday when the Chiefs (9-6) face Cincinnati in their final regular-season game. But Kansas City could still make the playoffs with a win and Pittsburgh loss to Detroit. Stiles, who was at meeting, said Vermeil appeared at peace with his decision. "I know so. ... It's the right thing for him to do, for his family, and it's the right thing to do for the organization," said Stiles, the Chiefs' vice president for football operations Vermeil's wife, Carol, told the AP that he was not available for comment.
