An article on the front page of tomorrow's (September 1) Daily Mirror is headlined "I Quit" and alleges that "Doctor Who's Matt calls time on Time Lord".
However, BBC Head of Communications Sam Hodges swiftly took to Twitter to play down the "over excitable headline", posting: "#DoctorWho fans - Matt Smith hasn't quit. See him in Asylum of the Daleks, tomorrow at 7.20 on #BBC1."
Explaining the context of the quotes featured in the newspaper, Hodges added: "[Matt] says in an interview that he won't be the Doctor forever - hardly quitting!
"He'll be around for a good while yet."
Responding to one user's accusation that the story is "probably a publicity stunt" designed to "hit that 7m overnight ratings target" ahead of the premiere of series seven, Hodges insisted: "Not at all - and we don't set targets like that."
Smith recently appeared to dismiss rumours that he will leave the BBC sci-fi drama in November 2013, teasing that the show's 50th anniversary is unlikely to feature a regeneration.
Doctor Who returns to screens on BBC One in the UK and BBC America in the US tomorrow night.
