Arnold Palmer is being hospitalized overnight after doctors noticed a rise in his blood pressure.
Alaistair Johnston, vice chairman of IMG and Palmer's longtime business manager, says the 82-year-old is on new medication and was checking his blood pressure throughout the final round. About 15 minutes before the tournament ended, doctors noticed enough of an increase to take him to the hospital for closer evaluation.
Johnston says Palmer was to be hospitalized overnight as a precaution. He says no one is overly concerned.
