ARLINGTON, Texas -- Dallas Cowboys linebacker Rolando McClain has been suspended indefinitely for violating the NFL's substance-abuse policy.

The suspension announced Friday likely ends McClain's career in Dallas and is his third since the end of the 2014 season, his only full season with the Cowboys after reviving his career following a year away from the game. He had a one-year contract this season.

The 27-year-old McClain was suspended the first 10 games this season for a substance-abuse violation after sitting the first four games in 2015.

McClain was eligible to return for the Thanksgiving game this season, but owner and general manager Jerry Jones said he wouldn't report to the team. Jones declined to be more specific.

The Oakland Raiders took McClain as the eighth overall pick in 2010 out of Alabama.
