Graham Onions is a doubt for England's fifth Ashes Test at the Oval on 21 August after breaking a little finger in
Durham's YB40 win against Scotland.
The 30-year-old seamer was in
Andy Flower's 13-man squad for the fourth Test at his home Emirates Durham ICG,
but was left out of the side.
He will miss YB40 games against Essex and Derbyshire with the injury.
If not selected for England, Durham hope Onions will be fit for Surrey's visit in the Championship on 22 August.
Onions, who has taken 58 wickets in domestic cricket this season, last featured for England in the drawn third Test against the West Indies at Edgbaston last year.
