Arnold Palmer has been released from hospital and allowed to return home after spending Sunday night under observation due to high blood pressure.
The 82-year-old - who won a total of seven majors - was taken to the Dr Phillips Hospital in Orlando on Sunday afternoon after feeling unwell during the course of the final round of the tournament he hosts at Bay Hill, the Arnold Palmer Invitational.
His admission to hospital meant he was unable to attend the traditional post-event prize ceremony and congratulate tournament winner Tiger Woods.
Preliminary tests at the course showed that Palmer was suffering from increased blood pressure - possibly from a change in medication - but doctors were satisfied enough with his condition by Monday to allow him home.
"They did a few tests this (Monday) morning, and he got home around noon," Palmer's long-time assistant Doc Giffin told the Orlando Sentinal.
"Other than being tired, he seems to be fine. The doctors told him to slow down - as much as possible."
Woods five-shot victory - the seventh time in his career he has won the event - was his first on the PGA Tour for two-and-a-half years.
