After missing the ongoing One-day series against the West Indies, Tendulkar yesterday pulled out of the Test matches as well and skipped a fitness test.
He told reporters that his shoulder was still weak and he had to make himself unavailable for the Test series.
Over the past 10 days, Leipus was closely monitoring Tendulkar's rehabilitation programme and now he would be getting the opinion of his friends in London on the cricketer's recovery.
''Sachin will keep in continued contact with Team physio, John Gloster, regarding his ongoing progress. In the meantime Andrew Leipus will endeavor to introduce Sachin to experienced colleagues of his in London who are well qualified to continue with his supervised rehabilitation,'' BCCI Secretary Niranjan Shah said in a statement.
Mr Shah said Tendulkar was recovering fast but had problems in playing some shots while his fielding and throwing programme are yet to begin.
''He has recovered exceptionally well given the time since the surgery and Dr Andrew Wallace (via telephone conversation) was confident that the repaired anatomical structures would be strong.
However, the important issue was whether he had recovered sufficient strength and muscular control to protect these underlying surgically repaired structures from the stresses of International cricket.
''Functionally, Sachin has returned to batting in the nets and although he appears to be coping very well, there is still considerable apprehension when playing certain shots. There are also subtle compensatory movements whilst batting which will potentially overload other structures (e.g. the elbow). In terms of strength, the shoulder is still considerably weaker than the left, predominantly in the biceps muscle,'' Mr Shah said.
''With regards to throwing and fielding, Dr Wallace only wants to begin a throwing programme in the next two weeks, and diving or landing onto an outstretched arm is still contra-indicated at present. These points alone indicate that the shoulder cannot be classified as being 100 per cent recovered.'' Tendulkar and Leipus have discussed this issue at length and both agreed on skipping the Test series against the West Indies.
Tendulkart would be re-assessed by Dr Wallace today to continue with his rehabilitation programme, he added.
