Regular between clubs have no longer been permitted since October 15 – and it will stay that way until the winter window opens on January 1.
However, several League One sides have still been completing business and bolstering their squad.
Clubs can still snap up free agents that are on the market, while emergency goalkeeper signings are also permitted.
We’ve taken a look at the players who have been on the move in the third tier since the summer transfer window closed.
