English cricket bosses have refused to comment on reports Test captain Andrew Strauss will retire.
The England and Wales Cricket Board (ECB) has called a media conference at noon, leading to speculation it will be to announce Strauss' departure.
Strauss, who captained England to the top of the Test rankings, has endured a tough 2012 culminating in a home series defeat to South Africa.
The Summer has been dominated by the ongoing row with Kevin Pietersen, who reportedly sent texts criticising Strauss to the South Africa players.
Pietersen was subsequently dropped for the final Test at Lord's, which overshadowed Strauss' 100th appearance for his country.
One-Day captain Alastair Cook is the favourite to replace Strauss as Test skipper, should he stand down.
Strauss has been the main stay at the top of England's batting order since making his debut in 2004. He has scored 7,037 Test runs, including 21 centuries.
