John Cena was embarrassed by The Undertaker at WrestleMania 34 in New Orleans, but the 16-time World Champion is hinting at a possible rematch for next month's SummerSlam pay-per-view.

Cena has the WWE Universe buzzing after he posted this photo on his Instagram page two days ago.

Earlier this week, the Wrestling Observer Newsletter reported that there have been more discussions about a Cena-Undertaker rematch. As of now, it's unclear whom The Deadman will face next month, and we're still awaiting confirmation that he will be competing at SummerSlam.

After spending a month of teasing a possible match on the Grandest Stage of Them All, Cena and 'Taker finally squared off in the middle of the ring. Despite the belief that Roman Reigns retired him a year ago, Undertaker came out and dominated Cena, winning their singles match in 2:45.

Undertaker then returned at the Greatest Royal Rumble pay-per-view and defeated Rusev in a Casket match, further showing that he's far from done in the ring and doesn't have any plans to retire just yet.

Thus far, only three matches have been confirmed for SummerSlam. Universal Champion Brock Lesnar will face the winner of Bobby Lashley and Reigns, and thus defend his title at the Barclays Center in Brooklyn.

Alexa Bliss is set to defend her Raw Women's Championship against Ronda Rousey, while A.J. Styles will defend his WWE Championship against an opponent that's to be determined.

Cena and Undertaker are arguably the two greatest and most accomplished superstars in the history of the WWE. Though their WrestleMania 34 match was short (and sweet, depending on who you ask), fans are clamoring for a longer, non-squash bout between the two legends.

WWE only has a few more weeks to announce its matches and buildup for SummerSlam, so we'll find out soon enough if Cena-Undertaker will happen again.
