Everton has dropped Jack Grealish from its squad for Thursday's Carabao Cup tie against Newcastle United, the club saying the omission was because of a "breach of club discipline," according to The Guardian.

The Guardian, in a report by Andy Hunter, said Everton took the unusual step of announcing the omission for disciplinary reasons on social media. The club made the announcement after listing David Moyes's team for the fourth-round tie, the newspaper reported. The Guardian also said Grealish was understood to have missed training.

BBC News reported that Grealish is left out of Everton's Carabao Cup tie with Newcastle United on Thursday "due to a breach of club discipline." The BBC report, as summarized, did not mention missed training or the social media announcement.

The two reports differ in detail. The Guardian described Grealish's absence from training as something the club's circumstances had made known to it, while the BBC item stated only the reason for his omission. The Guardian's account of the social media announcement and the training absence is not repeated in the BBC summary, so those points rest on the Guardian report alone.

The available summaries do not say what the breach of club discipline involved. They also do not include a comment from Grealish, and they do not describe any further statement from the club beyond the reason given for leaving him out of the squad.

Newcastle is the opposing side in the Carabao Cup tie. The fourth-round match is the stage of the competition described in the Guardian report. Neither source gives a score, a result or any update on Grealish's status beyond the squad decision for this match.
