The sports world is banding together to do everything it can to help the victims of Hurricane Katrina in Louisiana, Mississippi and Alabama.

Major League Baseball and the NBA each have pledged $2 million, and the Southeastern Conference is donating $1 million to disaster relief, as is the NFL.

MLB and its players' association and the NBA and its teams will give $1 million to the American Red Cross. In addition, the National Basketball Players Association has said it will raise $1 million to aid the relief effort.

In addition to the SEC's donation, the league announced Thursday that each of its 12 universities will coordinate fund-raising efforts at home football games during the next several weeks.

Baseball will pass collection plates at all 15 games Wednesday - Roberto Clemente Day - and has offered to match up to $1 million in proceeds. Players will wear Red Cross patches and bases will include the logo and a telephone number to call to contribute to the relief effort. The 15 visiting teams will host individual relief efforts on future dates.

Major League Baseball also announced a $1 donation for every item purchased at MLB.com.

The Atlanta Braves will donate $1 for every new ticket sold in the month of September to the Mississippi American Red Cross and hurricane relief efforts. The Braves and the Braves Foundation will donate a minimum of $100,000.

The U.S Tennis Association will donate $500,000 from U.S. Open proceeds to the American Red Cross for affected communities. The two players associations - the Sony Ericsson WTA Tour and ATP - said their members are donating autographed tennis equipment, apparel and memorabilia for an auction to aid victims of the disaster.

Meanwhile, where the New Orleans Saints will play this season was unclear.

NFL commissioner Paul Tagliabue said Thursday it's unlikely the Saints will play in New Orleans this season after the devastation Hurricane Katrina and its aftermath inflicted on the city.
