caliber pistol and tucked it into the waistband of his pants.
A Cedar Grove assistant principal saw Jarboe grab the gun and told school police to search Jarboe, Davis and the car.
Police said when Jarboe saw an officer approaching, he tried to hide the gun underneath the driver's seat of the car, where the gun was eventually found.
Police said the gun had been reported stolen.
Jarboe and Davis were taken to jail and later charged with bringing a gun to school and theft by receiving stolen property.
Both were later expelled from Cedar Grove, but Jarboe kept taking classes online to complete his high school degree.
In May, Cedar Grove football coach Ray Bonner stood up for Jarboe and contended that his former player was a "good kid" who had made a "bad choice."
"To paint that kid as an outlaw, that's not right," Bonner told The Oklahoman. "He feels like he let his family down, his teammates down, but he refuses to let any of this get the best of him. I know he's learned from this."
