South Carolina football shared Demetrius Knight Jr.'s reaction: "If you watch one 'call' video, watch this one," the caption read. "What a moment."

There's a reason linebacker Demetrius Knight Jr. was in tears when he got the call from the Cincinnati Bengals on Friday night. Back when Knight was playing college football for the Charlotte 49ers, he worked as a food delivery worker to provide extra money for his wife and daughter.

On Friday, the Bengals selected South Carolina linebacker Demetrius Knight Jr. with the 49th overall pick of the draft. A 25-year-old linebacker who spent six seasons in college, Knight tallied 82 combined tackles last season along with a pair of sacks and an interception.
