Newcastle United can confirm that Matt Ritchie has undergone a second operation on the ankle injury he sustained during the Carabao Cup clash with Leicester City in August.
Ritchie sustained the injury following a challenge by Foxes midfielder Hamza Choudhury and was forced to have an initial surgical procedure in October.
The 30-year-old will continue his rehabilitation on Tyneside and is expected to return to action in January 2020.
