Brock Lesnar broke The Undertaker’s streak at WrestleMania 30, took the WWE World Heavyweight Championship from John Cena at SummerSlam 2014 and seemed poised to wrestle in the main event of WrestleMania 31. Heading into his title match at Royal Rumble 2015, though, it no longer appears to be a certainty that the former UFC Champ will keep the title until the year’s biggest pay-per-view.

Rumors that Lesnar is headed to UFC when his contract expires after WrestleMania 31 have sparked speculation that he will drop the belt. The inclusion of Seth Rollins in the title match also seems to increase the chances of Lesnar losing his first match since 2013. Because Lesnar will put his championship on the line in a triple threat match with Rollins and John Cena, the “Beast Incarnate,” can drop the belt without being pinned.   

Lesnar remains the odds-on favorite to leave the Royal Rumble as the champ. According to Paddy Power, Lesnar’s odds of winning on Sunday are 4/9. Cena has the second-best chance of winning at 17/10, and Rollins’ odds are 7/1.

If WWE wants to keep Lesnar looking strong, he can win the match and still leave the Royal Rumble without the belt. Rollins has yet to cash in his Money in the Bank briefcase, which he could use on Lesnar, or Cena, if he wins the title.

Before The Shield broke up, it looked like Rollins might get lost in the shuffle, once the three wrestlers went their separate ways. Instead, his heel turn has allowed him to be the most successful singles star of the trio, quickly making his way to the top of the card. It’s very possible that WWE could put him in the main event of WrestleMania 31.

Considering the winner of the Royal Rumble will likely be a babyface, it might not make much sense to put the title back on Cena. However, the 15-time champ can never be counted out, and if he beats Lensar, he can lose the belt at February’s Fast Lane PPV.

Former WWE announcer Jim Ross isn’t very confident that Lesnar will retain the WWE World Heavyweight Championship, despite the odds.

After SummerSlam, Lesnar and Roman Reigns looked to be on a collision course to meet at WrestleMania 31. Now, there’s a chance that both will leave the Royal Rumble as losers. Reigns is still the favorite to win the 30-man battle royal, but there’s a chance that Daniel Bryan will be the last man standing on Sunday. Ross predicted Bryan as the winner of the match at

The WWE champion has retained the title at four of the last five Royal Rumble PPVs.
