Oakland Raiders receiver Andre Holmes has been suspended for the first four games of the season for violating the NFL policy on performance enhancing substances.

The league announced the suspension Saturday.

Holmes will be eligible to return to the Raiders' active roster Sept. 30. He will be allowed to participate in all preseason practices and games.

Holmes was claimed off waivers from New England in May. He played seven games for Dallas last season, catching two passes for 11 yards.
