In the week 14 game against the Kansas City Chiefs, McNair threw the longest regular-season touchdown pass in the Ravens' history, when he threw an 89-yard touchdown pass to receiver Mark Clayton, McNair helped Baltimore to a 13–3 record and an AFC North Championship. McNair started at quarterback in his first playoff game as a Raven when his team faced the Colts on January 13, 2007. McNair was 18 of 29 for 173 yards with no touchdowns and two interceptions, as the Ravens lost 15–6.
