Michael Phelps going to rehab after DUI arrest

Michael Phelps said Sunday that he's taking some time off from swimming and will attend a program after being arrested on DUI charges earlier this week. He made the announcement on Twitter.

Phelps, 29, was arrested and charged with driving under the influence Tuesday morning in Baltimore. He reportedly had a blood-alcohol content level of .14, nearly twice the legal limit.

It was Phelps' second DUI charge. His first came in 2004, when he was 19 years old. He pleaded guilty at the time and the judge gave him 18 months of probation but ended up waiving the conviction. With a second conviction, Phelps faces up to one year in jail, a $1,000 fine and a sixth-month suspension to his driver's license, according to an Associated Press report.

The Olympic swimmer announced his retirement from the sport after the 2012 Olympics in London, but began training this spring in the hopes of competing in the 2016 Games in Rio. 

He is due to appear in court on the morning of Nov. 19 to face five charges, including DUI, excessive speed, and crossing double lane lines.

Phelps is the most decorated Olympian of all time with 22 Olympic medals, including 18 gold.
