Who was the first person to wrestle the undertaker?

The Undertaker, Ted DiBiase, The Honky Tonk Man and Greg Valentine went against Koko B. Ware, Dusty Rhodes, Bret Hart, Jim Neidhart in a traditional Survivor series elimination match at WWF Survivor Series 1990 in Undertakers first match for the WWE. As for his first match of his career (WCW) I have no idea.
