Los Angeles Clippers head coach Doc Rivers is the latest sports figure to accept the #AllInChallenge, auctioning off a once-in-a-lifetime fan experience. As part of the initiative, 100 percent of proceeds will go to charities working to combat hunger and food shortages during the coronavirus pandemic.

Rivers announced he'll be auctioning off four “great” tickets to an upcoming Clippers game, along with the chance to be an assistant coach for the day. As an assistant, the lucky winner will be spending the day alongside Rivers, including taking part in morning coaches meetings, team shoot-around, in addition to pre-game and post-game media sessions.

Rivers is also offering the winning bidder two ball boy spots for their kids and a two-night hotel stay in Los Angeles.

“We have to raise money for the first responders, and also we have to raise money for food,” the Clippers coach said before outlining the prizes.

Doc Rivers then challenged Los Angeles Lakers head coach Frank Vogel to participate in the initiative.

Various celebrities, star athletes, and other public figures have teamed up to contribute over 90 auctions and over 70 sweepstakes to the #AllInChallenge so far. All the money raised from the auctions directly benefits non-profit groups such as Meals on Wheels, No Kid Hungry and America's Food Fund — which funds World Central Kitchen and Feeding America.

As of Monday night, the #AllInChallenge orchestrated by Fanatics has raised over $13 million and counting.
