Several weeks ago, Amazon.com posted the artwork for the SummerSlam 2014 DVD featuring John Cena and Brock Lensar. While it was assumed that this would be the SummerSlam main event, a match between the two superstars was technically not mentioned on the poster. Now, WWE commercial hyping John Cena vs. Brock Lesnar is airing in select markets across the United States, confirming the WWE World Heavyweight title match.
