It's unknown who will stand across the ring from Brock Lesnar at a jam-packed AT&T Stadium in Texas for WrestleMania 32 next year, but the field has at least been narrowed down.

Sting Talks Injury, Return To Ring

The four possibilities to face "The Beast" at the "Show of Shows" on April 3, 2016, are Seth Rollins, Roman Reigns, Dwayne "The Rock" Johnson and "Stone Cold" Steve Austin, according to The Wrestling Observer (via Cageside Seats).

Here's how each Superstar stacks up.

The Undertaker's 6 Worst Hell In A Cell Matches

Roman Reigns

The WWE had big plans for the former Shield member when he won the Royal Rumble Match last year, but angst from fans and overall greenness out of Reigns derailed things. Though there was no conclusion to the Lesnar-Reigns bout at WrestleMania 31, we've already seen them go up against each other at the big event, so it's time to move on.

Seth Rollins

The big question is whether or not "The Architect" will still be champion come WrestleMania. Like Reigns, we've seen Rollins and Lesnar square-off before, including at Battleground in July. That bout also didn't have a conclusion, since The Undertaker returned to cost "The Beast" the belt and cause a no-contest. This would be an outstanding bout, but with legendary names possibly coming back, it's not quite as enticing.

The Rock

"The People's Champion" is the man and a clash with Lesnar would be epic. These two crossed paths at SummerSlam in 2002, but both of them have changed so much since then. The Rock is a major movie star and Lesnar is a more formidable foe after a stint in the UFC. Paul Heyman's client won his first Undisputed Championship from The Rock that night 13 years ago, but a rematch all these years later would ignite AT&T Stadium.

"Stone Cold" Steve Austin

While the other three opponents would be compelling, no one would draw more than Austin, especially since he was never expected to wrestle again. Austin and Lesnar mixing it up in the ring would be a battle between two of the most legendary figures in WWE history. "The Rattlesnake" being a Texas native will also add to the proceedings as the place would explode.

Austin and Heyman hinted at a possible meeting between these two mega stars on the six-time WWE Champion's podcast, but quickly downplayed it. This match needs to happen at WrestleMania 32. This marquee matchup would shatter attendance records.
