Hodson, who came through the Reds’ Centre of Excellence, fell awkwardly in training earlier this week and will now miss the start of the 2018-19 season.
Ladies manager Scott Rogers said: “We are all devastated for Ashley but have no doubt that she will return better and stronger than ever once she has completed her rehabilitation.
“Ashley only has to look at players such as Amy Turner, who has returned from a number of serious injuries to perform at the top level. Ashley will have the full support of everyone at the club as she begins her rehabilitation process.”
