CBS released the list of castaways for Survivor Redemption Island on Monday, but they left out two of the names. Those mystery castaways are said to be former Survivor players and there are some pretty believable rumors on who we can expect to see back in the jungle. Read on if you don’t mind some spoiler speculation.

Jeff Probst told viewers that he would like to see Boston Rob and Russell Hantz go head to head one more time. Survivor fans have been speculating that we’d see those two castaways again ever sense the news came down from CBS that they’d be bringing someone back. So far that’s who we’re putting our money on.

If you could pick any two past castaways to return for the upcoming season of Survivor Redemption Island, which ones would it be?
