With the list of participating nations confirmed for January's
ATP Cup, several tennis stars are surprisingly missing from the entry list for the season's first event.
Leading the list of absentees is Spain's
Rafael Nadal, who withdrew from this year's US Open due to injury and has been recuperating ever since. Compatriot
Carlos Alcaraz is also missing from the entry list, as the Spaniard tested positive for Covid-19 a few days ago.
The American trio of
Reilly Opelka,
Frances Tiafoe and
Sebastian Korda have not been confirmed for the event, along with Russian
Karen Khachanov and Australians
Nick Kyrgios and
John Millman.
