Brock Lesnar is expected to win the WWE World Heavyweight Title and there’s been talk of Lesnar defending against Roman Reigns at WrestleMania 31, it’s still unknown how much Lesnar will be working besides SummerSlam, Night of Champions and a possible appearance at Battleground to put “plan B” in motion against John Cena.
It’s also expected that he would work Royal Rumble and WrestleMania 31 at least but there would be many dates he would have to work if he’s going to hold the title for several months.
