West Ham United striker Andy Carroll apologised to manager David Moyes and returned to training on Wednesday after he left the bench early in the loss to Manchester City on Sunday, according to the Press Association.
Carroll, an unused substitute, headed down the tunnel at the London Stadium before the end of West Ham's 4-1 defeat.
Sources told ESPN FC on Monday that Carroll had a heated argument with Moyes at the club's Rush Green training ground and was sent home by Moyes. With Tuesday off, Carroll returned to training on Wednesday and spoke with the manager, PA reported.
Moyes chose to send on Javier Hernandez, Joao Mario and Arthur Masuaku shortly after West Ham conceded a fourth goal after 64 minutes, leading to Carroll deciding to leave the bench.
"It's something I'll deal with," Moyes said at a news conference after the game. "In this situation, what you need is everybody to be a team member, so if [Carroll] has done that, I'll look at it and I'll deal with it."
West Ham, just three points clear of the drop zone, will resume their relegation battle at Leicester City on Saturday.
