Howard Beck of the New York Times reports:

Donnie Walsh, the Knicks’ team president, had surgery to repair his right hip Tuesday morning and is expected to spend a few days in the hospital before starting a rehabilitation program at home.

The Knicks did not provide a timetable for Walsh’s return, but he said last week that he planned to work from his Manhattan apartment during his recovery, which he figured would last about two weeks.

Glen Grunwald, the Knicks’ senior vice president for basketball operations, is with the team this week for its four-game trip through the Western Conference.
