KANSAS CITY, Mo. (AP) — Chiefs cornerback Sean Smith has been suspended the first three games of the regular season by the NFL after pleading guilty to a drunken driving charge earlier this year.

Smith, who was given two years’ probation, is entering a contract year after one of the best seasons of his career. He will miss games against Houston, Denver and Green Bay before returning for the Chiefs’ game against Cincinnati in Week 4.

The 28-year-old Smith started all 16 games for Kansas City last season.

Under the NFL substance abuse policy, first-time offenders receive two-game suspensions. But there can be additional discipline depending on the circumstances, and Smith was pulled over by police last year after his car struck and broke a light pole.
