Another main rivalry on the Raw brand heading into SummerSlam was between the returning Triple H against King Booker. At New Year's Revolution, during a World Tag Team Championship match between Rated-RKO (Edge and Randy Orton) and D-Generation X (Shawn Michaels and Triple H), Triple H suffered a legitimate torn right quadriceps during the match that left him out of action. On the July 16 episode of "Raw", Booker entered using Triple H's entrance music "King of Kings". Booker declared that neither Triple H nor Jerry Lawler could be known as "The King". On the August 6 episode of "Raw", Booker defeated Lawler in a match where the loser had to crown the winner the next week. When the time came, Lawler refused, declaring that Triple H was still a king and announcing that Booker would face Triple H at SummerSlam. Booker then attacked Lawler, throwing him into the ring post and hitting him with a television monitor.
