Kafelnikov struggles on

RUSSIAN Yevgeny Kafelnikov, struggling with a knee injury, beat Frenchman Cedric Pioline 7-5, 6-1 in the second round of the Kremlin Cup tennis tournament.

Kafelnikov said he may need surgery but planned to play in next week's ATP Tour Championship finals in Frankfurt first.

'The injury is really troubling me . . . but the Frankfurt tournament is incredibly important,' he said.
