India batsman Rahul Dravid has called a news conference for Friday morning in which he is expected to announce his retirement from international cricket.
The 39-year-old has scored 13,288 runs in 164 Tests since making his debut in 1996, second only to compatriot Sachin Tendulkar, and has made 36 centuries.
Dravid retired from one-day cricket last September, having scored 10,889 runs in 344 internationals.
He will continue to play in the Indian Premier League Twenty20 tournament.
Former skipper Dravid, nicknamed "The Wall" for his patient batting style, also holds the world record of 210 Test catches.
India were the number one side in Test and one-day international cricket in 2011 but have dropped to third in both categories and have been whitewashed 4-0 in their last two Test series in England and Australia.
With Dravid and fellow batsmen Tendulkar and VVS Laxman all in their late 30s, calls have been made for younger players to be introduced.
Dravid enjoyed a successful 2011 with five Test centuries, but averaged a modest 24 in Australia, passing fifty only once in eight innings.
Board of Control for Cricket in India president N Srinivasan will also be in attendance at Friday's news conference in Bangalore.
