Travis Kelce's quiet offseason finally has a bit of noise in it ... the Chiefs tight end was spotted out in Georgia over the weekend -- getting in a training session with some high school football stars.
The 34-year-old, who's kept a low-profile since February, hit up Chamblee Charter H.S. to run some routes with NFL legend Jamal Lewis' son, Jazz, and take a look at a pic the younger Lewis posted following their workout -- Kelce sure got his sweat on.
