Tiger Woods has said alcohol was "not involved" in his arrest on suspicion of driving under the influence.
The former golf world number one was held near his home close to Jupiter Island in Florida.
He was booked into jail shortly before 7.20am on Monday and released nearly four hours later, Palm Beach County Police said.
In a statement, Woods said alcohol was not a factor in his arrest on suspicion of driving under the influence, and instead blamed an unexpected reaction to prescribed medication.
The 14-time major winner is currently recovering from recent back surgery.
However, the 41-year-old said he took full responsibility for his actions and apologised to his friends, family and fans.
"I want the public to know that alcohol was not involved.
"What happened was an unexpected reaction to prescribed medications," he said.
"I didn't realise the mix of medications had affected me so strongly."
Woods had only returned to competition, after a 15-month absence through injury, in December.
Plans to participate at Augusta in April, on the 20th anniversary of his first Masters victory, also had to be abandoned.
He last won a major in 2008, and in 2009 was charged with careless driving near his home after crashing into a tree and damaging a fire hydrant.
Woods later admitted to extra-marital affairs and made an apology in early 2010 in which he spoke of undergoing therapy, saying he was "far short of perfect".
