It appeared to be a precautionary move, and is understood to have been due to stiffness in his lower back. Stokes decided not to risk doing further damage, with Gus Atkinson brought in to complete the over, Stokes remained on the field through to lunch. New Zealand were bowled out for 254, with Brydon Carse taking 6 for 42 for 10 wickets in the match, leaving England a modest chase of 104 for victory at Hagley Oval.
It is understood that the injury is unlikely to affect his availability for the second Test, which starts in Wellington on Friday.
He stepped up his workload with Durham in the County Championship after opting out of selection for the T20 World Cup. The decision allowed him to operate as a full allrounder in the West Indies series at the start of the summer, with 49 overs and five dismissals taking him past 200 wickets in his Test career.
Speaking ahead of the first Test against New Zealand, Stokes said he was now “good as gold” and “completely over” the hamstring injury: “The amount of physical work that I put my body through over that nine, ten-week period definitely had its toll, probably over my whole body…I’m completely over the injury and ready to go again.”
