The Oklahoma State football team will for the rest of the season don special helmet decals as a tribute to the late T. Boone Pickens, Stadium’s Brett McMurphy reported Wednesday.

Pickens, who donated $652 million to Oklahoma State, with much of it going to the football program, passed away Wednesday at his home in Dallas, Texas.

Oklahoma State will honor T. Boone Pickens with a helmet decal the remainder of the season. Pickens, 91, died today. He will be buried at Karsten Creek Golf Club, Oklahoma State’s home golf club — Brett McMurphy (@Brett_McMurphy) September 11, 2019

It’s unclear what the special decal will look like or where it will be located on the helmet, but in 2016 to honor those who died in the tragic homecoming parade and in the plane crashes, the Cowboys donned 18 football stickers on the back of the lids — one for each victim.
