Forward Sean Elliott has been hospitalized with the flu, team doctors said.
Elliott, who underwent a kidney transplant last summer, was admitted this past weekend to Methodist Hospital in San Antonio. He is expected to be released today, said Dr. David Schmidt, the team doctor.
"It was purely a precautionary measure," he said. "When you are on those types of medications (to fight rejection of transplanted organs), it is a little more difficult for you to fight infection."
Elliott, who serves as a color commentator for Spurs telecasts, is not expected to return until the Jan. 5 home game against the Seattle SuperSonics.
He has said he is optimistic he will rejoin the team as a player.
