London:Former England captain Michael Vaughan is to hold a media conference on Tuesday, with British media predicting that the 34-year-old batsman will announce his retirement from the game.
Vaughan, who has captained England to more test wins than anyone else, including the victorious Ashes series against Australia in 2005, has been plagued by right knee injuries in recent years.
Last week he was left out of a 16-man training squad for this year's Ashes, having struggled to find form for Yorkshire in the county championship - scoring just 147 runs in seven first class innings this season.
Yorkshire chief executive Stewart Regan said on Sunday: "Without going over old ground, Michael had set his stall on being picked for the Ashes Tests... When that didn't happen I think it then opened up a different set of thought processes over what happens next.
"He will discuss his future with his employers tomorrow and a press conference will be held on Tuesday."
Vaughan was England's captain in 51 of his 82 Tests, winning 26 of them.
But he hasn't played international cricket since relinquishing the captaincy in 2008, having made his England debut against South Africa in November, 1999. He has scored 5,719 runs in Test cricket and 1,982 in 86 one-day internationals.
