Aces' Monfils out of Hopman Cup with leg injury

PERTH, Australia — Gael Monfils has withdrawn from the Hopman Cup mixed team event due to an unspecified leg injury and will be replaced by French compatriot Kenny De Schepper.

It was not clear whether the injury would prevent the 24th-ranked Monfils from competing in the Australian Open beginning Jan. 18 in Melbourne.

Hopman Cup tournament director Paul Kilderry said Thursday "it's unfortunate to hear Gael is unable to play in Perth ... we wish him well over the next couple of weeks ahead of the Aussie Open."

De Schepper and his partner Caroline Garcia play their first match Monday against the Britain team of Andy Murray and Heather Watson.

Serena Williams and Jack Sock open for the United States, also on Monday, against Elina Svitolina and Alexandra Dolgopolov of Ukraine.
