The "Oracle" logo was seen being removed Thursday afternoon at Oakland's Oracle Arena.
No other information was immediately available, but Golden State Warriors fans took to social media to officially mark the end of an era.
The arena, affectionately dubbed by fans as "Roaracle," will no longer be home to the Warriors. The team next season will start playing in its new home at the Chase Center in San Francisco's Mission Bay.
According to Oakland mayor Libby Schaaf, the site will continue to host concerts and sporting events.
No announcement has been made as to what the arena's namesake will become.
