49ers star Aldon Smith suspended 9 games by NFL

San Francisco 49ers linebacker Aldon Smith is in the news again for all the wrong reasons. He's been suspended by the league for the first nine games of the 2014 NFL season.

Smith has a list of past transgressions in the NFL that led to this discipline. He was arrested this offseason for allegedly yelling "bomb" in an airport. Smith also missed five games in 2013 while being treated for substance abuse.

In May, Smith pleaded no contest to a trio of felony weapons charges and a misdemeanor count of DUI that occurred last year. Even though he avoided prison time, the NFL was poised to take action, and they've done so by suspending him under the personal conduct policy.

NFL commissioner Roger Goodell did say last October that he'd take into consideration how Smith voluntarily missed five games last season while seeking substance-abuse treatment.

As a rookie in 2011, Smith was named Defensive Rookie of the Year by Pro Football Writers of America, and finished second to Von Miller for the Associated Press NFL Defensive Rookie of the Year Award.

In 2012, Smith broke one of Reggie White's many NFL record by recording 31.5 sacks in his first two seasons. Hi 19.5 sacks that year also topped Fred Dean's 49ers franchise record of 17.5 sacks in one season.

Because Smith missed five games in 2013, he only managed to get 8.5 sacks.
