According to latest reports, WWE is planning to do a match between Brock Lesnar & Kevin Owens at SummerSlam 2015. WWE officials are planning to push Kevin Owens to the main event picture.
Kevin Owens is expected to drop the NXT Title to Finn Balor on the July 4 Network Supercard in Japan & is scheduled to face John Cena for the WWE United States Title at the Battleground PPV in July.
There’s no information available as of now regarding the match between the two being for the WWE World Heavyweight Title. It likely won’t be for the WWE World Title as Rollins is expected to be the WWE World Champion through at least October. Below is a statement from the Wrestling Observer:
The latest direction for SummerSlam appears to a Lesnar vs Owens match up. It’s felt that within the inner circle of WWE that Owens is being prepared to be shot to the top of the main event scene. The only question mark is whether this match will be a title match. At present the current direction is to continue with Seth Rollins as champion through at least October. However plans can change, so Lesnar vs Owens may be for the title.
