WWE.com: WWE Fans at the 2005 Hall of Fame and all over the world chanted, "One more match." You delivered that to them tonight. Was this Hulk Hogan’s last match?
Hulk Hogan: Well, I am not thinking about that at this moment. It was a great night for Hulk, Shawn and all of the WWE fans. I feel really good right now. It will really be a tough decision. It’s so hard to give up what you love doing. Hanging up the boots will not be an easy thing to do.

"If the hip is OK after this one, I might consider a return on a part-time basis to complement the current roster,''said Hogan.
At the Backlash PPV, there was no mention of retirement. Everyone just assumed that because of all the "one more match" chants, that's what it was. But in all actuality, that's not a fact.
