Back injury scare for Sampras

Pete Sampras pulled out of an exhibition match with a back injury - but is expected to be fit to play at Wimbledon

The 30-year-old was due to play Stefan Koubek at the Boodle & Dunthorne Championship in Buckinghamshire.

However, Sampras felt a "slight tweak" in his back while practising and felt it was better to rest rather than aggravate the problem.

Sampras is seeded sixth at Wimbledon this year.
