East Hampton Village Mayor Paul F. Rickenbach Jr. will take a leave of absence from his role in village government for medical reasons, he said by phone on Friday.
“I’ll be undergoing a knee replacement surgery a week from today,” he said.
In the interim, Deputy Mayor Barbara Borsack will serve as mayor until Mr. Rickenbach’s return.
The length of his leave is indefinite. “I’m cautiously optimistic,” he said. “It depends on the recuperation time, but I hope to be back soon.”
