Could B.J. Penn's return to combat sports actually happen?
Based on this picture "The Prodigy" posted to his Instagram account alongside Greg Jackson -- one of the greatest minds in mixed martial arts (MMA) -- he may already be walking the comeback trail.

We coming !! @ufc @danawhiteufc
Penn retired from the sport of MMA after suffering his third loss to Frankie Edgar at The Ultimate Fighter (TUF) 19 Finale in 2014, which also marked his third straight defeat.
Just a few months ago, however, the former Ultimate Fighting Championship (UFC) lightweight and welterweight champion declared he'd be willing to step back into the Octagon to put a beating on Nik Lentz.
