The Untouchables S02E24 - Ring of Terror

When boxer Joey McGrath dies in the ring, the medical examiner reports no special circumstances and the Press put it down to a tragic accident.

McGrath's manager Barney Jarreau is a straight arrow who wasn't involved in the fix but with the McGrath incident about to be reviewed, numbers racketeer Rudy Krasna decides to force Jarreau's hand to fix an upcoming championship fight.
