The gentle exodus of players from Zimbabwe continues with news that Gary Brent and Terry Duffin are believed to have quit international cricket.

Brent, 32, played 70 one-day internationals and four Tests for Zimbabwe but was increasingly at odds with the board, and was one of the rebels who went on strike following the sacking of Heath Streak as captain in 2004. Although he did make a comeback, he is said to have grown frustrated with the attitude of the national selectors and last month gave notice on his contract.

Duffin, 26, was Zimbabwe's captain until 2006 and played 23 ODIs and two Tests. His last major match was during the 2007 World Cup and since then he has struggled with injury, although he represented Zimbabwe Provinces in South Africa as well as Southerns in the domestic Twenty20 tournament in March.

It is thought that he applied for the board's permission to play club cricket in England but this was refused, even though he is not in the main national squad. Duffin travelled to England anyway where he is playing for Winsley in Wiltshire, and it is reported that he will go to New Zealand rather than return to Zimbabwe at the end of the season.
