LONDON, Oct 26 (Reuters) The Queen cancelled plans to open Arsenal Football Club's new London stadium today because she has a strained muscle in her back.
But a spokeswoman at Buckingham Palace said: ''There is no cause for concern'' for the monarch who has just returned from a three-country trip to the Baltic states.
The 80-year-old monarch was advised by doctors to reduce her workload for the day but she is still going ahead with an audiences with ambassadors at her London residence.
The Queen had been scheduled to meet Arsenal manager Arsene Wenger and captain Thierry Henry on a tour of the new Emirates stadium. Prince Philip will now go ahead without her.
Buckingham Palace said the normally sprightly octogenarian had sustained the back injury while staying at her Balmoral country residence.
''It has not improved during a busy two weeks of engagements,'' the spokeswoman added.
''Doctors advised Her Majesty to reduce her workload today and will review her progress on a daily basis,'' she added.
