In February 1948, rumours began to circulate that Carter was to move to
Leeds United. Carter was interviewed for the position but there were two stumbling blocks, the length of the contract and Leeds' wish to make the appointment at the end of the season. On 1 April 1948, Carter joined
Hull City in a player / assistant manager role for £6,000. He turned down other offers believing he would learn more under manager Major
Frank Buckley and Hull City would provide the fastest route into a manager's position. He was appointed player – manager on 23 April 1948 after Buckley's resignation. Carter continued his playing career at
Hull City, winning the
Division Three North title and reaching the Round 6 of the
FA Cup in his first season and buying a young
Don Revie. In the next 2 seasons, the side finished 7th and 10th in
Division Two. On 5 September 1951, Carter offered his resignation. It was accepted by the directors on 12 September 1951, no reason was given and no discord was apparent. Several clubs expressed an interest in signing him but he continued to train with
Hull City, who retained his playing contract, until the directors asked him not to. He maintained his match fitness by playing local amateur football in
Leconfield. Following strong public support, although not all the directors were not supportive, he returned as a player with
Hull City on 8 December 1951 for the rest of that season before retiring as a player. In May 1953, Carter was appointed
Leeds United manager; he stated he was joining as manager only, although he did play in several friendly games. In his first two seasons, they finished 10th and 4th in
Division 2. In May 1955, Carter turned down an offer to return to
Derby County as manager. He was rewarded with a new 3-year contract to replace the 2 one year contracts he'd previously had. In 1956,
Leeds United finished runners-up and were promoted to
Division 1 after a nine-year absence. The following season, they finished 8th in the top flight with
John Charles scoring 38 goals. He left for
Juventus FC in the summer. The following season, without his goals,
Leeds United finished 17th. On 9 May 1958, the chairman, Sam Bolton announced Carter's contract would not be renewed, saying,"it was with regret that the decision had been reached" and there were tears in his eyes when he said it. The decision was a shock to Carter. In February 1960, Carter was appointed as
Mansfield Town manager. He could not save them from relegation to
Division 4 in his first season. A younger, rebuilt side finished 20th and 15th in the next 2 seasons. After a good start to the 1962/3 season, he was linked to
Cardiff City in October 1962. On 11 January 1963, he left to become manager of
Division 2 Middlesbrough. In 1964, Raich presented a young Philip Lowery with his town colours for Stockton Town Football club. The young team he left behind were to gain promotion back to
Division 3 at the end of that season. At
Middlesbrough, his team finished 4th,10th and 17th before they parted company with Carter on 12 February 1966 when in 20th place. Subsequently, they dropped into the relegation places and were relegated at the end of the season. == Style of playing and management ==
