The Argentinian – who has twice beaten testicular cancer - was not even named among the substitutes for Sunday’s 3-1 defeat at home to Spurs.
Afterwards, Carver said Gutierrez was left out for ‘selection reasons’ before stating that he did not want to talk about the player.
The 31-year-old had earlier posted a message on Twitter saying that he was not injured.
Indeed, sources close to Gutierrez say that he was axed following a heated exchange with Carver.
Gutierrez was upset when he was dropped from the starting XI for last week’s 3-0 loss at Liverpool. He had been United’s best player during the Tyne-Wear derby defeat at Sunderland in the previous game and was surprised by his omission, which was explained as a tactical switch to pair Jack Colback and Mehdi Abeid in midfield.
What followed was a training-ground disagreement with Carver and Gutierrez tweeted on Thursday, ‘I am tired about some things. I am Geordie. Newcastle deserves more’.
Gutierrez’s contract is up in the summer and he will be let go after seven years at the club. The clause which meant he would be guaranteed an extension after eight starts this season cannot now be activated.
