Major U.S. professional sports organizations are adding a financial boost to relief efforts following Hurricane Katrina.

The National Football League says it is donating $1 million to the American Red Cross to assist hurricane victims in Louisiana, Mississippi and Alabama. The NFL also says it is working on other ways to assist.

The National Basketball Association and Women's NBA are combining their aid efforts. Players are making donations and helping directly with the U.S. Federal Emergency Management Agency. The American Red Cross is raising money at WNBA playoff games in Los Angeles and Indiana.

Major League Baseball teams are also gathering money and donating items to help. Clothes and non-perishable food items were collected Wednesday at Dodger Stadium in Los Angeles.
