There are less than two weeks until WrestleMania and things are really starting to heat up in the WWE. The card is almost set - with this week's episodes of Raw and Smackdown Live confirming a number of huge matches. Daniel Bryan - GM of the blue brand, has worked his way into a tag-team match with Shane McMahon against Kevin Owens and Sami Zayn. "The Beard" has recently been cleared for an in-ring return, and it's fair to say fans are very excited for his return after he's been out of action for over two years. Although some matches are only just being confirmed, WrestleMania's main event has been set for a month. At the top of the card, Brock Lesnar will defend his Universal Championship against Roman Reigns. "The Big Dog" earned his shot after winning the Elimination Chamber match back in February - but taking Brock's title will be far from easy.   Lesnar refused to show up on Raw for a number of weeks, leading to Reigns verbally taking shot after shot, even calling his opponent "Vince's boy" amongst other things. But last week, the Beast finally made an appearance and jumped his challenger inside the ring. While Reigns was handcuffed and being led out of the arena, Brock took his moment. The segment ended with Roman being taken away on a stretcher. Advantage Lesnar. This Monday, Brock's advocate Paul Heyman opened the show by shooting on Reigns - and it was one of his best promos in recent memory. He suggested that the title challenger was too much of a coward to turn up after the beating he took a week before - but of course, that wasn't the case. Before Heyman could finish, Reigns emerged from the crowd with a steel chair in hand. He got a few decent shots in before Lesnar turned the tables on a still clearly injured Roman. This time, the segment ended with Reigns taking an F-5 on the steel steps. He's now had two bad beatings in the space of a week and the momentum is clearly with Lesnar heading into WrestleMania. But apparently, things are going to get even worse for Reigns. Well, that's according to Heyman, who fired a warning on Twitter this afternoon.He quoted a WWE video of Reigns returning to Raw but suggested that the beatings will continue to come, with the worst coming on April 8. 

Ouch. Apparently Roman's going to have to watch his back if he's even going to make it to WrestleMania. But on the Grandest Stage of Them All, anything can happen.
