Brock Lesnar Challenges Kofi Kingston for the WWE Championship at SmackDown on Fox Premiere

Former Universal Champion Brock Lesnar made a surprise return on SmackDown Live to challenge Kofi Kingston for his WWE Championship.

Lesnar was accompanied by his advocate Paul Heyman after the six-man tag match between The New Day, The Revival and Randy Orton. Heyman informed Kingston that Lesnar was formally challenging him for the title at the Fox SmackDown Live premiere on October 4.

Kingston, who told Big E and Xavier Woods to leave the ring before Lesnar arrived in the ring, got on the mic and reminded the WWE Universe that he promised to be a fighting champion when he won the title at WrestleMania. Kofi tells Lesnar and Heyman that he gladly accepts the challenge.

An elated Lesnar puts out his hand, but quickly picks Kingston up and hits the champion with an F-5.

Brock Lesnar was last seen at SummerSlam where he lost his Universal Championship to Seth Rollins. Before that, Lesnar won the Money in the Bank briefcase and cashed-in on Rollins at the Extreme Rules pay-per-view.

Kofi Kingston won the WWE Championship from Daniel Bryan at WrestleMania 35, the same show where Lesnar lost his Universal Championship to Seth Rollins. Kingston would defend the title against Bryan, Dolph Ziggler, Kevin Owens and Randy Orton over his five-month reign.

WWE is putting out all the stops for the first SmackDown on Fox. It was announced that the first episode will celebrate the 20th anniversary of the blue brand. There are scheduled appearances from WWE Hall of Famers and past superstars including Kurt Angle, Lita, Mick Foley, Booker T, Hulk Hogan, Trish Stratus, Goldberg, Jerry Lawler, Mark Henry, Ric Flair and Sting.

The first episode of Friday Night SmackDown will be preceded by the next WWE Draft, where members of the roster will be split between Monday Night RAW and SmackDown. The events of Hell in a Cell on October 6 and the first episode of Friday Night SmackDown could affect who goes where.

In March 2018, reports that WWE and Fox were in agreement to bring SmackDown to its channels surfaced. NBCUniversal reportedly declined to keep the blue brand on USA, which opened up the possibility for another channel to buy it.

Fox's deal with WWE is reportedly for five years worth $205 million annually. The deal was made official in June with the WWE also announcing a five-year extension with NBC to keep Monday Night RAW on USA.
