After their seventh game on October 9, 1960 at Jeppesen Stadium, his teammate Howard Glenn died. Barnes asked for his release two days later. The cause of Glenn's death was reported as a broken neck. However, Barnes and other teammates have long attributed it to heatstroke. In a later interview, Barnes said, "They never really said what he died of. (Coach) Sammy Baugh said he'd broken his neck in a game the Sunday before. But how could that be? How could he have hit in practice all week with a broken neck? What he died of, I think, was more like heat exhaustion. I told them I didn't want to play on a team like this."
