Sami Zayn Returns to WWE Main Roster at Monday Night Raw, Attacks Kevin Owens

Sami Zayn is back on the main roster.

The high-flying NXT star made his return to WWE Monday Night Raw to intervene in the post-match altercation between intercontinental champion Kevin Owens and Neville.

After Owens picked up a victory over Neville in a non-title match, Owens was about to powerbomb Neville outside the ring before Zayn interfered. 

This is the first time Zayn has been on Raw since May 4, 2015, when he faced John Cena for the United States Championship.

After undergoing shoulder surgery, which had kept him out since May, Zayn made his return to WWE as a participant in the Royal Rumble match. Although he didn't win a spot in the main event at WrestleMania, Zayn has been involved in the main event picture in NXT since his return.

Zayn and Samoa Joe are involved in the NXT championship picture, with general manager William Regal trying to figure out who will be Finn Balor's next challenger for a possible title shot at NXT TakeOver in Dallas.

WWE Hall of Fame ring announcer Howard Finkel reacted to Zayn's return to Raw:

Bleacher Report's Mike Chiari thought Zayn's return set up a classic match for WrestleMania:

WWE's biggest question will be figuring out what to do with Zayn. Monday's actions could result in Zayn and Owens meeting for the intercontinental title as the two stars rekindle their NXT rivalry.

But while Zayn wants to become the first two-time NXT champion, his involvement with Owens could ensure Joe faces Balor in a rematch of their battle at NXT TakeOver in London. Zayn's return to the main roster was overdue, but it should heighten NXT's intrigue going forward.
