"That's an absolute lie," Moore said on Monday afternoon, adding for emphasis, "an absolute lie. It's a lie."
According to published reports, the Royals were talking to the Indians about dealing infielder-outfielder Teahen to the Indians for either outfielders Franklin Gutierrez and Ben Francisco or Trevor Crowe, a Minor Leaguer.
"Not only have I not been discussing it, but it's a flat-out lie and you can print that," Moore said.
According to the stories, the Indians were interested in Teahen because he could fill their hole at third base, created when Casey Blake was traded to the Dodgers.
On the Royals side, the speculation was that David DeJesus would be switched permanently to left field with the incoming Gutierrez, Francisco or Crowe taking over center field.
Moore said he and Indians general manager Mark Shapiro have not discussed any such deal.
Asked if he'd have interest in any of the three Indians outfielders, Moore said he couldn't comment because they were part of another team.
"When people ask me direct questions, I like to give them direct answers, but I don't want to tell them because I don't know what can or can't take place or how things are going to unfold. I just don't know," Moore said.
"If Mark Shapiro wanted to make Franklin Gutierrez or Ben Francisco available, he'd have several teams, I'm sure, interested and not just the Kansas City Royals. ... But I can't comment on the our level of interest or the value of a potential player to us."
Speaking generally, he said there are no trades imminent for the Royals.
"We're just talking to other teams about what their goals for the offseason are and just trying to filter through, to see if there are any matchups," Moore said.
"We always have things we're working on, but I don't think anything is going to happen today and, obviously, we're in the World Series and you can't make an announcement on anything anyway."
