According to The Wrestling Observer Newsletter, there may be some concern from WWE officials regarding the match between Roman Reigns and Universal Champion Brock Lesnar heading into WrestleMania 34, specifically regarding the steroid ring accusations that have been brought against Reigns over the past month or so.
Although Reigns has completely denied these accusations, filmmaker Jon Bravo claims that he has evidence about it that he will release soon. His evidence allegedly involves Roman Reigns, along with several other past and present WWE Superstars.
If there is any truly damaging evidence that comes out against Reigns, WWE officials are reportedly looking at Braun Strowman as a back-up option in case the match with Brock Lesnar needs to be changed. It was previously reported that Strowman would likely have an Intercontinental Championship Match against The Miz, but those plans may have been scrapped.
