Was it Undertaker's last bout in the ring?

ORLANDO, Florida -- It was an emotional rollercoaster of a night during Wrestlemania 33, and it left many fans wondering if it was The Undertaker's last bout in the ring.

One of WWE's most famous and legendary stars appeared to have retired after he lost to Roman Reigns. Many fans shed a tear when The Undertaker went out in style after he took off his gloves, hat and trenchcoat and placed it in the middle of the ring.

#ThankYouTaker started trending on Twitter with people thanking The Undertaker for entertaining them for years.

Meanwhile, WWE's version of the Super Bowl also saw John Cena take a knee.

Cena stole the show when he seemingly gave a real proposal to Nikki Bella at the end of their victorious mixed tag team match. Cena got down on one knee after the pair defeated The Miz and Maryse on Sunday at WrestleMania 33 at the Citrus Bowl.

Bella said yes and the couple , who star on "Total Bellas," celebrated with family at ringside. Cena and Bella are both scheduled for the "Today" show Monday morning. Cena is a regular on the show and weatherman Al Roker was the guest ring announcer for the bout.

Rob Gronkowski took a break from rehabbing for the New England Patriots and got involved in the Andre the Giant memorial battle royal to help his real-life buddy Mojo Rawley win the event. Gronkowski watched from the front row until bad guy Jinder Mahal tossed a drink in the tight end's face. Gronk, who celebrated in the Daytona 500 victory lane with Kurt Busch, charged the ring and snapped into a three-point stance to take out Mahal and help Rawley win.

WWE announced a crowd of 75,245 at the Citrus Bowl, though those numbers are usually inflated for entertainment purposes.

Brock Lesnar, the former UFC heavyweight champion, defeated Bill Goldberg in the bout of the night to win the WWE Universal championship.

Reigns defeated The Undertaker , in perhaps his last match, in the main event of a card that stretched seven hours.

Other major results include:

- Randy Orton defeated Bray Wyatt to win the WWE world heavyweight championship.

- The Hardy Boyz made a surprise return to win the WWE Raw tag team championships. Matt and Jeff Hardy, WWE stars in the late 1990s and early 2000, had reinvented themselves in other promotions as "broken" characters who were on an expedition for tag team gold.

- Seth Rollins defeated Hunter Hearst Helmsley in a no-holds barred match.
