"I'm feeling pretty good," Hester said. "You know, I came out and ran around a little today and broke a sweat."
According to Hester, the groin injury didn't occur on a single play. The soreness accumulated during the first week of camp until the wideout required rest for a few days.
"It just kind of built up," Hester said. "When you're working hard, things like that tend to happen. Coach always says if you don't get hurt in training camp you're not working hard enough. I guess I'm working hard."
Hester was medically cleared and dressed in full-pads for practice Tuesday night.
