CM Punk to defend Undisputed WWE Championship against Cody Rhodes at SummerSlam

CM Punk appeared on "Friday Night SmackDown" ready to take on any challenger that was ready to step to him after winning the Undisputed WWE Championship against Sami Zayn.

Punk entered the ring in Oklahoma City and called back to the "Monday Night Raw" after WrestleMania 42 when he told Cody Rhodes he’d be ready to deliver if a championship opportunity fell "out of the sky."

"When championship opportunities fall out of the sky, CM Punk catches them," he said.

Punk named potential SmackDown superstars he’d think might come for the title, including Gunther, Finn Balor, Royce Keys, Damian Priest and Trick Williams. He even said that Zayn could come back around and get his rematch if he wanted. He didn’t mention Rhodes’ name, but the "American Nightmare" came out uncalled and marched his way down to the ring.

"I don’t think you and I can run away from each other anymore," Punk told Rhodes.

Rhodes agreed and mentioned that Punk would want a match with him, just "say when." It was a quick retort from Punk, who said, "when." SmackDown general manager Nick Aldis, who was in the ring for the segment, booked the match for SummerSlam.

Punk will defend the Undisputed WWE Championship at SummerSlam, which takes place Aug. 1 and 2 at U.S. Bank Stadium in Minneapolis.

First, however, Punk and Rhodes will be involved in a tag team match at Saturday Night’s Main Event in New York City next week. Aldis made the match after Gunther demanded that Aldis put him in a match against Punk. Gunther was hoping it would be for the championship. Instead, Gunther will tag with Zayn.

Gunther didn’t take too kindly to that and attacked Aldis. Rhodes came back out to break up the calamity. He wanted to take on Gunther after the show went off air but Gunther walked away.

Punk definitely has his hands full as he moves to SmackDown to become a fighting champion.
