Lamar Odom checked out of a rehab center Thursday about a day after seeking help for drug problems, sources tell PEOPLE.
The pro basketball player, 32, checked into the drug and alcohol center on Wednesday morning and left Thursday afternoon with an assistant, according to two sources. Odom was later spotted in Los Angeles.
Odom has a history of drug issues. He violated NBA drug policies twice in eight months back in 2001, and spoke in 2003 of his marijuana use.
