Utah coach Kyle Whittingham noted it's for a great cause.
"It's for something that's far more important than football," he said. "And so I'm hoping that people step up and do that."
UnderArmour created the black jerseys with camouflage trim in support of the Wounded Warrior Project, a non-profit group that assists U.S. service personnel injured in combat.
The so-called "blackout game," where fans also were encouraged to wear black, had a patriotic theme. Wounded veterans served as honorary captains, and 50 active and retired soldiers held a huge American flag across the field during the National Anthem. In addition, 25,000 flags were handed out to fans.
