Stillwater, Okla. ? Billionaire booster T. Boone Pickens will give another $63 million to Oklahoma State to finish athletic projects that were supposed to be paid for with a previous $165 million donation that took a hit during the economic downturn.

Pickens announced the gift Monday and also said he would be returning the $125 million remaining in the athletic department’s fund to the university.

Pickens’ $165 million donation in January 2006 was the largest gift ever given to a college athletic program. He intended to grow it through his investments so it would pay for about $420 million in renovations and new construction on the campus.
