The Wrestling Observer Newsletter had reported that WWE Universal Champion Brock Lesnar was set to face Roman Reigns in the main event of the August 19th WWE SummerSlampay-per-view, which could be where Lesnar drops the title. This would also likely be his last match for WWE under this run as his contract is expiring.
A new update reported by The Observer reports this week that Reigns vs. Lesnar for SummerSlam is not a done deal, as of this past weekend. Furthermore, Lesnar has not been confirmed for SummerSlam by Vince McMahon at this point. It was also noted that Lesnar has not been confirmed for any other WWE dates. Lesnar is said to be aware of this but unless things have changed in the last day or two, officials have not given the green light for his ring return.
