John Cena is making another return to WWE. WWE sources tell us Cena is set to appear on the Sept. 1 edition of SmackDown, taking place at The Giant Center in Hershey, Pennsylvania. As you'll recall, the 16-time World Champion last stepped in the ring back in April at WrestleMania 39, when he challenged Austin Theory for the United States Championship. Cena was in control for most of the match, but ultimately lost after receiving a low-blow, then an "A-Town Down" from the champ.
