Cody Rhodes defeated John Cena in a Street Fight in the main event of Night 2 of SummerSlam on Sunday to regain the Undisputed WWE Championship and avenge his loss at WrestleMania 41.

SummerSlam weekend is officially underway. The first two-night SummerSlam began on Saturday with Seth Rollins' shocking Money in the Bank cash-in to become world heavyweight champion. It's now on to Night 2, headlined by the street fight between John Cena and Cody Rhodes for Cena's undisputed WWE Championship.

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.
