The National Football League granted Heerfs Grant of $1.7 million to a nonprofit organization that will use it to help the families of former San Francisco 49ers defensive end David Mayo and linebacker Anthony Davis, according to a source familiar with the process.

The NFL said that the Grant was granted by the U.S. Treasury Department’s Office of Thrift Supervision on April 16.

Mayo was diagnosed with lung cancer last year and died at age 46 on March 25.

Davis is recovering from a knee injury suffered in a 2013 collision with Dolphins wide receiver Kenny Stills.

The grant was approved by the NFL’s Board of Governors on March 18.

It will be used to assist Heerfe family members in paying rent, utilities, food and other expenses, the source said.

Heerf family members have donated $6.8 million to help their daughter, Brittany, finish high school and to help with her medical expenses, according a source.

The family has also given about $3.6 million to various charity initiatives, including the Heerff Family Foundation.

This is the third grant awarded to Heerfa family members since May, according for NFL Commissioner Roger Goodell.

In April, Heerfo and his family were awarded a $4.5 million grant to help help the family with rent and other costs.

And in May, the Heers’ son, Ryan, was awarded a grant of $3 million to cover his tuition at the University of North Carolina.
