History

Historical Context

In September 1991, Michael Watson collapsed after his WBO super-middleweight bout with Chris Eubank, receiving medical aid only after 28 minutes and later undergoing six brain operations. The High Court held the British Boxing Board of Control negligent, prompting stricter on-site protocols and tighter medical checks. A similar brain bleed forced Irish Boxing Authority doctors to deem Glenn Byrne unfit after his April 3 knockout loss.
