Brock Lesnar made a shocking return to WWE Sunday night at SummerSlam-- hitting John Cena with his F5 finisher to close the show.
MetLife Stadium erupted when the former WWE Champion's music hit the speakers. Lesnar stared down Cena as he made his way to the ring ... setting up a showdown between the two amid Cena's retirement tour.
His appearance came as a shock to many ... as the 48-year-old was named in the lawsuit filed by Janel Grant against Vince McMahon in 2024.
