Adrian Peterson is at it again, giving away more of his money to help others.

The Vikings' All-Pro running back, who had already established his "All Day Foundation" for the benefit of at-risk youth, has now pledged $1 million to his alma mater, the University of Oklahoma.

Peterson's donation will support the construction of Headington Hall, which is a new student housing facility, and the creation of the "Adrian Peterson Football Scholarship Endowment.

In recognition of the donation, OU will change the name of the football team meeting room from "The Red Room" to "The Adrian Peterson Team Meeting Room."

"This was something that I had been thinking about doing for a long time," said Peterson, who played at OU from 2004 through 2006 and is OU's third-all-time-leading rusher. "I always hoped to be in a position to be able to donate back to the University of Oklahoma and make it an even better place; do whatever I could to help the university that did so much for me.

"It was something that I always wanted to do and there just came a time when I got established and comfortable enough to make it happen. It was a no-brainer to do it and I am thankful that I'm in a position to give back to OU and to show my appreciation."

Said Sooners football coach Bob Stoops: "Adrian is certainly special. He possessed great natural ability, but never took that ability or his teammates for granted and it was common for him to place the interests of others above his own. I'm excited that his name will appear in Headington Hall to remind others of his example of selfless dedication and generosity. I'm also grateful to him for helping us continue the great Sooner legacy."

Among his other charitable ventures, Peterson also has teamed with actors Ashton Kutcher and Demi Moore in their effort to end human trafficking of children.
