Lesnar, who was named in the federal lawsuit against former WWE chairman Vince McMahon, attacked Cena after Sunday's conclusion to the two-event weekend.

At one point, Cena came up through the elevator shaft on the entrance way with Rhodes on his shoulders and walked him back to the ring. That exhausted him enough for Rhodes to take advantage. He removed a bottom turnbuckle and blasted him over the head with the steel piece.

Cody Rhodes is once again undisputed WWE champion. Rhodes outlasted John Cena in a lengthy, hard-fought SummerSlam Night 2 main event on Sunday to regain the championship he lost to Cena at WrestleMania. But it was Brock Lesnar's return to WWE after the main event that will be the main talking point for many.
