NFL: Cardinals' Washington suspended four games

The National Football League slapped Arizona Cardinals linebacker Daryl Washington with a four-game suspension on Wednesday, saying he violated the league's substance abuse policy.

The NFL declined to provide further details on why Washington was suspended.

Washington, who is considered one of the young stars on the team, is banned from playing in the first four games of the regular season.

"I was always taught that when you make a mistake, you admit it, learn from it and face whatever consequences there are," Washington said in a statement. He also declined to go into further detail about why he was banned.

Washington, 26, earned his first Pro Bowl appearance last season after recording a career-high 134 tackles, nine sacks and an interception in 16 games.
