PERTH, Australia (AP) -- Wimbledon semifinalist Jerzy Janowicz has pulled out of the Poland team for this month's Hopman Cup with a foot injury.
Janowicz was to team with women's No.5 Agnieszka Radwanska at the annual international mixed team tournament in Perth, Australia, which serves as a warm-up for January's Australian Open. He will be replaced in the draw by Davis Cup teammate Grzegorz Panfil.
Janowicz said he injured his foot a couple of weeks ago and was hoping to be fit in time to play.
''Poland will be making its debut at the event and I wish Agnieszka the best of luck.''
John Isner, Sloane Stephens, Jo-Wilfried Tsonga, Petra Kvitova, Sam Stosur and Bernard Tomic are among the field for this year's tournament from Dec. 28 to Jan. 4.
