DK Metcalf didn't advance to the finals in his professional track debut, but the Seattle Seahawks wide receiver fared better than some expected.

With an official time of 10.37 seconds, Metcalf finished last among the nine in his heat and 15th among the 17 who competed in the USA Track and Field Golden Games and Distance Open in Walnut, California.

"These are world-class athletes," Metcalf said. "They do this for a living. It's very different from football speed, from what I just realized. So, like I said, just excited to be out here."
