Signs at Shearer's Bar were removed on Thursday, hours after the club's record goalscorer used his column in a national newspaper to criticise the appointment of Joe Kinnear as director of football and the resulting fall-out.
However, the development was a coincidence and the start of a major redevelopment programme which will see the bar reopen in July as Nine, a move about which finance director John Irving claimed the club had "liaised" with Shearer.
The former striker is adamant he had not been consulted over the name change but said he was not unduly bothered by it.
"There was no consultation, I was simply informed by email of their decision to change the name," he said in The Sun. "It was not a question of me agreeing or disagreeing.
"It is their ground and it is up to the owners what they do with it. It won't stop me from buying my season tickets and supporting the team."
Shearer's Bar opened in December 2004 during Freddy Shepherd's reign as chairman.
The striker scored 206 goals during a 10-year spell with his home-town club, eclipsing Jackie Milburn's record in the process.
