Turns out a little penis (not really) can take you a long way ... or at least for NFL prospect Chris Jones ... whose combine wardrobe malfunction just netted him a year of free undies!!!
By now you've seen the video ... the big DT from Mississippi State had a little mishap during his 40 ... falling flat on his face ... and flashing a little (not really) frank & beans in the process.
Well PSD underwear wants to make sure that never happens again ... and President Curt Flaitz tells TMZ Sports they plan to keep Jones' boys snug .
