The 24-year-old tore the meniscus in his right knee during City’s Premier League clash with Swansea City on October 27, and subsequently underwent surgery, which ruled him out for four months.
Richards is cautious not to set an exact return date and admits it's frustrating for him to be on the sidelines rather than assisting his side’s title defence, but is hopeful of coming back stronger than ever.
"I am not putting a date on when I will be back because these things are never exact but I am hoping it will be in early February," he told the club’s official website.
"There is still not too much I can do but I am now on one crutch instead of two so that is progress.
"Of course it is frustrating and there is nothing more I would like than to be out there playing but I am being well looked after, the injury is responding and the knee getting stronger every day."
