Quarterback Patrick Mahomes spent some time before Saturday's preseason game running up and down the Kansas City Chiefs sideline, yelling, jumping and psyching himself up for his first game action since last season's Super Bowl.

"This pass," he said, "is coming my way." Brownlee made a heck of a touchdown catch, the highlight of the Chiefs' 20-17 loss to the Cardinals in the preseason opener here in Arizona - and, ahem, most certainly the highlight of the 48 seconds Patrick Mahomes spent on the field.

The Kansas City Chiefs dropped their preseason opener at home to the Arizona Cardinals. Patrick Mahomes wasn't a reason for the loss.
