Conor McGregor appears to have announced a highly-anticipated return to UFC in December.

The 31-year-old has not fought since his high-profile defeat to Khabib Nurmagomedov last October, where he lost his UFC lightweight title.

McGregor has posted a cryptic tweet saying "Dublin, December 14th", which may be suggesting a date for his return to the cage.

Since his last outing, McGregor has been faced with a number of issues outside the sport and only recently confirmed he would be returning.

McGregor's potential opponent could be Justin Gaethje, who knocked out Donald Cerrone, and said afterwards he would "love to" fight McGregor.
