For those who have been paying attention to "The Young and the Restless" over the years, they will know that Tucker McCall was actually played by current "Days of Our Lives" star Stephen Nichols, according to Soaps in Depth. Fans know him best as a businessman who has managed to romance the high-powered Jill Abbott and was also revealed to be Katherine Chancellor's long-lost son. Soap Central also noted that he was married to both Ashley Abbott and Sharon Newman and had flings with the likes of Harmony Hamilton and Diane Jenkins.

Just recently St. John told Michael Fairman TV that before he joined the cast of "The Young and the Restless," he actually didn't do his homework on the character, and that's because of a specific reason. He said, "Since Tucker has been away from Genoa City, it's safe to say he has a lot of ground to cover when it comes to re-establishing relationships, most importantly with his son, Devon. We will also see Tucker form some new alliances as well."

If that wasn't enough, he also teased that fans will have to "strap in" for all of the drama that's ahead. In other words, St. John's version of Tucker McCall will differ greatly from what we've seen with Nichols' portrayal of the character. Something tells us that he's got more than just secrets about Diane Jenkins to unload.
