Edge kicked off the SmackDown before SummerSlam and sat down in the ring before saying he heard everything Seth Rollins said last week. He said that Seth was threatening him the same way he did in 2014 and that Rollins could end his career with the stomp at SummerSlam."I know that if you hit that Stomp it probably ends my career." - @EdgeRatedR to @WWERollins #SmackDown pic.twitter.com/ek8w7uZ9G5— WWE on FOX (@WWEonFOX) August 21, 2021Edge added that Seth took him to a dark place, and at SummerSlam, he would 'break' Rollins and humble him before rephrasing that he will 'Burn him down'."At #SummerSlam, I am going to BURN. YOU.
