Several athletes and professional sports teams have already pitched in to aid the victims of Hurricane Harvey in Houston and nearby areas, but the outpour of support won’t be stopping any time soon with Dirk Nowitzki also joining in to help the relief efforts.

The Dallas Mavericks star announced via Twitter that he will give all proceeds from his charity tennis tournament, the Dirk Nowitzki Pro Celebrity Tennis Classic, to the families affected by Harvey.

The event is scheduled for September 16 and will take place at the SMU Tennis Center. Professional tennis players Andy Roddick, Tommy Haas, and Mark Knowles are all confirmed to participate together with actor Owen Wilson and Mavs guard J.J. Barea, among others.

This is just the second year that Nowitzki and his foundation will host the charity event. The inaugural tournament last year featured actor Ben Stiller as well as the Mavs' prized signing Harrison Barnes.

Dirk Nowitzki is among the growing list of NBA players that have extended a helping hand to support the cause. Just recently, Golden State Warriors point guard Stephen Curry pledged $118,000 while Hall of Famer and former Rockets star Dikembe Mutombo donated $50,000, among others.

Thunder forward/center Enes Kanter has also chipped in and even called out to people on social media to take action.
