Captain Joe Root has said that England players will be rotated and rested during the hectic 2021 calendar year in which they play 17 Test matches beginning with the series in Sri Lanka in mid-January.
England play two Tests in Sri Lanka and follow it up with four Tests in India -- six Tests over a period of eight weeks.
They play their first Test in the Indian sub-continent from January 14-18 in Sri Lanka and their last from March 4-8 in India.
