Laura Robson sustains shoulder injury

Laura Robson has injured her shoulder playing for Great Britain in the Fed Cup.

The 19-year-old needed the trainer during her singles win against Greta Arn of Hungary.

After the match, the world number 45 told British Tennis: "After the first set I thought, this can't get any worse. I regrouped and played better in the second and third sets."

Heather Watson also won her singles match, to set up a promotion playoff with Bulgaria tomorrow.
