LEEDS:- Ben stokes is a doubt for the second Test against Sri Lanka, on his home ground at Chester-le-Street, after suffering a knee injury at Headingley. stokes took to the field at the start of day three but, after a few overs, reported discomfort and returned to the dressing-room for treatment. He did not bowl, as England wrapped up an innings-and-88-run victory, but remained at the ground and did not go for a scan. He had briefly left the field for treatment on day two after jarring his left knee while bowling.–Agencies
