Robinson appeared to injure his right hamstring during Wednesday's minicamp practice, Jourdan Rodrigue of The Charlotte Observer reports.
According to Rodrigue, Robinson went down hard while running a route and had to limp off to the sidelines. The receiver was later seen with a bag of ice strapped to his leg, but Robinson didn't need to leave the field. It's possible the 30-year-old could be held out for the remainder of minicamp with the intention of preparing him for the start of training camp in late July.
