Survivoris honoring the life of one of its own.

At the end of Wednesday night’s episode, the CBS reality competition series included a memorial card dedicated to Rudy Boesch, the season 1 contestant whodiedat age 91 last week.

“ASurvivoricon. An American hero,” the card read, alongside a photo of Boesch on the show.

The show’s Twitter account also shared the memorial card, adding, “You will be deeply missed, Rudy” with heart and flag emojis in the caption.

PEOPLE confirmed on Friday that Boesch had died after a long battle with Alzheimer’s disease.

Boesch, a former Navy Seal, was cast on the inaugural season of the long-running reality show in 2000. Then 72, Boesch finished the season in third place and quickly became a fan favorite due to his lovably cantankerous persona. He also competed onSurvivor: All-Starsand was the second person voted out.

“It didn’t take long for Rudy to become my favorite human, not only in the game ofSurvivorbut also in life,” Kelly Wiglesworth told PEOPLE. Wiglesworth was the runner-up of the first season, and she was in an alliance with Boesch.

“We started to get to know each other on that island and with each day, I liked him more, we liked each other more. We would pass each other in the early dawn light every morning, both of us running laps to keep our physicality up,” she said. “He would talk, lovingly about [his wife] Marge and their daughters and how he was doing this for them and that at 72, he wasn’t in this game for himself and that he had nothing to prove.”

Meanwhile, Richard Hatch, the winner ofSurvivorseason 1,tweeted: “Ours was an interesting bond, Dear Rudy! You and I helped open minds and undermine predjudces [sic]. While your time here has passed, you will remain loved and iconic, dear friend!”

“We lost an original OG@survivorcbs legend,” addedRob Mariano, better known to fans as Boston Rob, who shared that he felt “fortunate to have known him” and played alongside him inSurvivor: All Stars.

“Rudy was always very nice to me,” he continued. “Our Sincere condolences to his Family. Rest In Peace Rudy.”

Posting a photograph from their time together,Survivor: All Starscontestant Rob Cesternino, who spent weeks with Boesch after they were voted out of the competition, reflected on the “many, many laughs” they shared.

“I heard the news today about my old roommate RUDY BOESCH passing away. While I’m incredibly sad for the Boesch family, I’m so happy for the time that he and I shared and the many, many laughs we had on our adventure. RIP Rudy,” he wrote.

Survivor: Australiawinner Tina Wesson was also on a tribe with Boesch onSurvivor: All Stars— and was amazed at the then-75-year-old’s stamina.

“He has always had the respect of every young whippersnapper who came out to playSurvivor. Because none of us could do what he did at his age!” Wesson added.
