Raducanu was also announced among the six shortlisted candidates on Monday morning for the BBC's Sports Personality of the Year but had already been intending to miss the ceremony and is currently in the United Arab Emirates ahead of the Abu Dhabi tournament.
The BBC has drastically cut the number of those invited to its Sports Personality of the Year show in the wake of the Government's new coronavirus restrictions.
