As of the 2013-2014 NFL season, the lightest NFL player was Trindon Holliday, who weighed in at 170 pounds. Listed at just 5'5", Holliday was also the shortest player in the NFL at the time.
A wide receiver and return specialist, Holliday excelled in track and field during his collegiate career. He was selected in the sixth round by the Houston Texans in the 2010 draft. In one of his finer efforts as a pro, he once returned a punt for a 90 yard touchdown and a kickoff for a 104-yard touchdown in the same game against the Baltimore Ravens.
