Simon Byrne "The Emerald Gem" and "Champion of Ireland" fought Sandy McKay "The Champion of Scotland" in 1830.
McKay died from a punch to the throat:
The result of the fight attracted wide publicity and led to rioting in the streets of McKay’s homeland. In Dundee, three people died and 200 were injured in the fracas. In Glasgow, four people died, and the Dragoons were called out to quell rioting after a Roman Catholic church was burned and looted, (as an Irishman the mob would have assumed Byrne to be a Roman Catholic). Byrne was arrested three days later aboard the ferry to Ireland as he tried to leave the country. He was returned in chains to Buckinghamshire and incarcerated in Buckingham Gaol to await his trial, and the prospect of the gallows.
