HOUSTON (AP) - Houston Texans left tackle Duane Brown has been suspended for four games for violating the NFL's policy on performance enhancing drugs.
Brown said Tuesday he "unknowingly took a supplement tainted with a banned substance." Brown's suspension begins immediately, meaning he will miss the undefeated Texans' showdown Sunday with the Dallas Cowboys. His first game back will be Nov. 1 at Indianapolis.
The former first-round pick has the crucial role of protecting the blind side of Texans quarterback Matt Schaub. Brown held his own in a season-opening battle with Colts All-Pro end Dwight Freeney.
The Texans are already without linebacker Brian Cushing, who was suspended for four games for the same infraction. He is eligible to return Oct. 10, when Houston hosts the New York Giants.
