According to reports in Russia, Sadiq reportedly began to cough up blood after his defeat by technical knockout, having needed an oxygen mask straight after the fight in Khimki, near Moscow.
The 32-year-old was said to have fallen ill during a routine doping check. He was given immediate medical assistance by doctors, according to Russian publication TASS.
The boxer has since allayed fears of a serious injury after replying, “I am good, thanks” to a message posted by South West boxing media on Twitter.

Sadiq represented Nigeria at the 2016 International Boxing Association African Olympic qualification event in Cameroon, but failed to book an Olympic ticket.
Sadiq’s defeat is his second in a 12-fight career so far. The pugilist took the fight on a three-week notice against the former WBA super-middleweight champion.
Chudinov (23-2-16), is now on a nine-fight winning streak.
