New York Knicks and Rangers owner James Dolan has been hospitalized and is expected to undergo heart surgery Monday.

The 50-year-old CEO of Cablevision -- which owns the Knicks, Rangers and Madison Square Garden -- checked into a hospital Saturday to prepare for bypass surgery.

"His physicians expect him to make a full and complete recovery," the company said in a statement.

Dolan led a successful fight this past summer against New York mayor Michael Bloomberg to block the development of a stadium and convention center in midtown Manhattan. The company felt that the stadium, a key component of the city's failed Olympic bid and prospective home for the New York Jets, would have competed with the Garden.
