Is The Undertaker’s legendary WWE career over? It sure looked like he announced his retirement at the end of WrestleMania 33 on Sunday night.

Shortly after losing to Roman Reigns at the WWE’s premier event—which was just his second WrestleMania loss of all time—The Undertaker took off his gloves, jacket, and hat and left them in the middle of the ring. He also climbed out of the ring and kissed his wife Michelle McCool. And he seemed to savor the moment as he walked back up the ramp and headed for the locker room. He didn’t say anything, but he did spend a long time soaking up the love he received from the crowd. You can see for yourself here:

Undertaker’s gear remained in the middle of the ring for quite some time, too. Long after fans had left Camping World Stadium in Orlando, Florida, his gloves, jacket, and hat were still sitting there:

The WWE hasn’t issued a formal announcement about Undertaker’s future just yet. But Undertaker—who is 52 now and has been wrestling for WWE for almost 30 years now—has struggled with a handful of injuries in recent years, so the thought is that we may have just seen him wrestle for the final time.

Following his match with Reigns, his fellow WWE wrestlers and personalities responded to the news of his apparent retirement by starting a #ThankYouTaker tribute on social media:

And it didn’t take long for fans to start using the hashtag, too. By early Monday morning, #ThankYouTaker was the top trending topic on Twitter. Here are some of the tributes that fans have sent out:

If this is the end for Undertaker, it has been one hell of a ride for him. #ThankYouTaker
