This year's "Royal Rumble 2018" match only has a few entries with John Cena arguably the biggest name to enter so far. However, if the latest betting odds are anything to go by, there may be a few other WWE stars from the past, present, or future making a surprise in-ring appearance in the men's match.

As indicated by Paddy Power's betting odds, most names leading the list of potential surprise entrants are a number of superstars already associated with the WWE in some capacity. Topping it are "The Showoff" Dolph Ziggler and Kane, who have both been featured in WWE storylines recently. In fact, the latter is actually set to appear in the Tripple Threat match.

Kane hinted last month that the upcoming "Royal Rumble" pay-per-view could be his last. Talking to New York Post, Kane said while he believes he still performs at a high level, he has been in WWE for around 22 years now and he may not have many opportunities left.

"This might be the last one. I don't know," he admitted. "I certainly think the match at Royal Rumble is going to be special for me." That said, it makes sense for him to show up in the match he has achieved historic stats with.

Other superstars likely to also appear include Chris Jericho at 3 to 10 odds, and Pete Dunne and Triple H at 1 to 2 odds. Andrade "Cien" Almas (4/6), Killian Dain (5/6), and Ricochet (5/6) are among the top options, too. Check out the full list below:

Of course, the odds are by no means any guarantee, but they are not entirely groundless as well. Wrestle Zone notes that the source was one of the first bookmakers to reveal that Randy Orton was the top favorite to emerge victorious on last year's "Royal Rumble." Fans will have to wait and see.

"Royal Rumble 2018" is scheduled for Sunday, Jan. 28, from Philadelphia, Pennsylvania.
