Octagon veteran Forrest Griffin joined the never-ending UFC injury list, and will no longer participate in the co-main event bout with Phil Davis at UFC 155.

Griffin has completely wrecked his knee, tearing MCL and straining his ACL tendons. Thirty-three year old fighter was hoping to make a statement against Davis, but will now have to face a long-term recovery. UFC President Dana White confirmed the news on Twitter:

It is yet to be determined whether the UFC will be able to find a replacement for Griffin, as not many fighters are overly excited to get inside the Octagon with Phil Davis on short notice. This could be an interesting opportunity for a fighter like Jimi Manuwa, who impressed MMA fans around the world with a dominant performance against Kyle Kingsbury back in September.

Forrest Griffin was originally scheduled to face Chael Sonnen at UFC 155, but this fight was scrapped after Sonnen was 'promoted' to face Jon Jones in April. UFC 155 injury list also includes Chris Weidman and Gray Maynard.
