A spokesperson for Repton Boxing Club in east London, where the Zambian-born athlete had previously trained, described him as a "powerful boxer" and "crowd pleaser" who always achieved an "all action humdinger of a bout" even in his amateur days.
The club said: "We are saddened to hear that Ex Repton Boxer Michael Norgrove has died nine days after collapsing in the ring at The Blackfriars Venue London, doing what he loved."
His promoter Steve Goodwin tweeted: "It's so unbelievable what has happened to this young man."
