Colin Edwards will miss the final MotoGP race of the season in Valencia as he awaits surgery on a broken arm.
The 37-year-old American was injured in the accident in which Marco Simoncelli was killed in Sepang on 23 October.
Edwards returned to Houston, Texas, for checks which showed multiple fractures to his left arm.
The American rider said: "I wanted to be in Valencia next week to give my support to MotoGP but it is not going to be possible."Reuse content
