Nicola Adams: Two-time Olympic champion retires over fears for her sight bbc.com

Britain's two-time Olympic champion Nicola Adams retires from boxing over fears she could lose her sight.

The Briton, 37, became the first female Olympic champion when she won gold at London 2012, retaining her flyweight title at Rio 2016.

She turned professional in 2017 and is the WBO world flyweight champion.

"I've been advised that any further impact to my eye would most likely lead to irreparable damage and permanent vision loss," said Adams.
