The Dazed and Confused star was taken into custody for disorderly conduct and assault on 27 January (13) after allegedly punching a bouncer at the Martini Ranch bar in Scottsdale and getting aggressive with police who arrived at the scene.

London has maintained his innocence ever since, claiming he was a victim, and now he has undergone a procedure to repair a deep nasal fracture and severe orbital floor fracture, as well as have a titanium plate inserted into the right side of his face.

And it appears his medical problems are far from over - editors at TMZ.com report the 40 year old still needs to have orthopedic and ocular surgeries and it will be a ""very long time"" before he recovers.
