Fever hits Murray's fading chances of making Davis Cup

The prospect of Andy Murray being fit to play in the Davis Cup tie against Serbia and Montenegro in Glasgow this weekend suffered another setback yesterday when the British No 1 was struck down with a fever and swollen glands. He already has an ankle injury.

While Murray said he would decide tomorrow if his ankle is up to playing Davis Cup - he could face three five-set matches in as many days - Jeremy Bates, the British captain, can delay naming a replacement until an hour before the draw at noon on Thursday. The team includes Greg Rusedski, Arvind Parmar and James Auckland.

If Murray pulls out Bates might try to persuade Tim Henman to play. With Alex Bogdanovic "not mentally ready", the next-ranked Briton available is Martin Lee, the world No 253.

Murray, Rusedski and Henman have slid in the new ATP world rankings. Murray (45) and Rusedski (49) dropped four and one places respectively, while Henman's fall by seven to No 63 could prevent his entry in the main draw of some Masters series tournaments this summer.

The new No 5, Ivan Ljubicic, runner-up to Roger Federer in Miami on Sunday, will now play in the Stella Artois Championships at Queen's Club in June.

Wimbledon is to issue 850 new debentures for No 1 court. Costing £12,250 each and valid for five years from 2007, £10.4m should be raised for improvements including a retractable roof over Centre Court.
