San Francisco Giants left fielder Barry Bonds was indicted Thursday for charges of perjury and obstruction of justice.

He is accused of lying to a federal grand jury about his “unknowing” use of performance-enhancing drugs. If convicted on all five counts, the 43-year old Bonds could go to prison for 30 years.

The indictment, which culminates a four-year investigation into steroid use by elite athletes, charged Bonds with four counts of perjury and one of obstruction of justice. If convicted, he could be sentenced to a maximum of 30 years in prison.

However, Bonds is not the only professional athlete in trouble with the law these days. Here are three other athletes facing legal trouble as well:

1. O.J. Simpson – The former Buffalo Bills running back will go on trial for charges of kidnapping and armed robbery, among other charges. The trial could start in as early as 60 days. The 60-year-old former football star could face life in prison.

2. Adam “Pacman” Jones – The suspended Tennessee Titans corner back had his plea deal accepted by a judge Thursday. Jones will have felony charges against him dropped to a gross misdemeanor of conspiracy to commit disorderly conduct in turn for his testimony about a triple shooting in Las Vegas.

3. Marion Jones – The former five gold medal winner in the 2000 Sydney Summer Olympics admitted steroid use. Jones was forced to give back all of her medals, prizes and points from the event and was suspended for two years, though she retired from track and field on the same day she admitted her use of steroids.
