Michael Madsen is tapped by FX's The Mob Doctor -- TV Guide reports.
Madsen will play Russell King, a veteran criminal whose crimes require a certain flair and professional expertise. On the night of a big job, King has a flare-up of back pain and discovers he requires immediate surgery. We're guessing The Mob Doctor herself, Jordana Spiro's Grace Devlin, will be called on to help.
Madsen will appear on the current season's ninth episode.
'The Mob Doctor' airs Friday, 9pm on FX.
