UFC lightweight champion Anthony Pettis has suffered another knee injury, but this time, it won’t force him to miss any Octagon time.

UFC president Dana White confirmed news of the injury on FOX Sports 1, adding that “Showtime” is still a go for December and a title defense vs. Josh Thomson.

Pettis defeated Benson Henderson this past August via first round submission to secure the title. His bout at UFC on FOX vs. Thomson will be initial title defense.
