Orton was then attacked by The Singh Brothers, but fended them off. Mahal then attacked Orton with the Khallas.[16]

She was confronted by the champion, and SmackDown Commissioner Shane McMahon decided that if Flair could defeat Naomi in a non-title match, she would be granted a title match the following week, which she did. This angered Natalya, Tamina, and Carmella (with James Ellsworth), as they each felt that they should have been the number one contender.[11] The following week, Flair and Naomi's title match ended after they were both attacked by Natalya, Tamina, and Carmella.[12]
