Arthur Blank, owner of the NFL’s Atlanta Falcons and Atlanta United of MLS, announced on Thursday that his foundation will match fan contributions up to $1 million when they donated to the Red Cross Disaster Relief Fund.

Blank is calling on fans and supporters of both clubs to join the relief effort for those affected by the unprecedented flooding and devastation caused by Hurricane Harvey.

“Our thoughts and prayers go out for the people of Houston and surrounding areas as they begin a long recovery from the impact of this terrible disaster, as well as the heroes that have sprung into action showing us great courage and again reminding us of the very best of America,” said Blank. “The work and resources needed by the people there are going to be almost unimaginable so we hope the incredible fans of both of our teams will join us by giving whatever they can to support our brothers and sisters in a time of incredible need.”
