OWINGS MILLS, Md. (AP) Ravens rookie linebacker Arthur Brown will be sidelined for at least a month while he recovers from sports hernia surgery.

Brown, the Ravens' second-round draft pick, had the operation two weeks ago following the team's first rookie minicamp. He did not practice Wednesday at a voluntary offseason camp and is also expected to miss the mandatory three-day minicamp that begins June 11.

He is expected to be fully recovered by the time Baltimore begins training camp in late July.
