SAN DIEGO (AP) - The NFL says San Diego Chargers defensive tackle Garrett Brown has been suspended without pay for the team's first four regular-season games for violating the league's policy on performance-enhancing substances.
Brown, who signed as a free agent, will be eligible to return to the Chargers' active roster on Oct. 1.
The league says Brown is eligible to participate in all preseason practices and exhibition games.
General manager A.J. Smith didn't immediately return a call seeking comment.
