Hull City have sent Marlon King back to parent club Wigan Athletic.
King had been on a season-long loan from Wigan but the agreement was terminated after a dispute between the player and manager Phil Brown.
King took exception to Brown's decision to leave him out of the starting line-up to face Arsenal last week and was consequently left out of the squad altogether. He has since agreed to join Middlesbrough on loan.
Brown said: "As far as I am concerned, whenever I pick a team it is for the right reasons.
"For one player to disagree with that in front of the rest of the players is not the way forward for my changing room, hence the reason we decided to part ways."
King scored five goals for Hull during his time at the club but Brown suggested he was not impressed with the player's overall contribution.
When asked if he was disappointed how events had transpired given how well King had played, Brown replied: "That's opinion."
Brown has also dismissed reports linking him with a loan move for another Wigan striker, Henri Camara.
