James Dolan late Tuesday pushed out two of the top executives in charge of running his over-budget music venue slated to open in Las Vegas this fall, The Post has learned.

The Knicks and Rangers owner plans to personally oversee the completion of the $2.2 billion MSG Sphere, a source told The Post.

Dolan paid for a pricey Super Bowl ad during Sunday’s game promoting the new venue and its first act, U2. The high-tech MSG Sphere, which has been saddled cost overruns, is now slated to open in September.

To get to the finish line, Dolan dumped MSG Sphere President Lucas Watson and MSG Sphere Senior Manager of Business Operations Jenna Wolfenson, according to an internal memo reviewed by The Post.
