Ben Stokes and Gus Atkinson have received written warnings about their future conduct after both were cleared to return to England's squad for the third Test against New Zealand.
With Stokes and Atkinson back in the 15-man group, England have released Sonny Baker, James Rew and Henry Crocombe. Baker and Rew made their debuts at The Oval, where England were beaten by 253 runs, but both struggled to make an impact - Baker taking 3 for 161, Rew scoring 24 and 15, as well as enduring a tough baptism behind the stumps.
Jordan Cox, England's third debutant, was initially called up as cover for Stokes but retains his spot ahead of Rew, effectively as the spare batter and wicketkeeping cover.
Brendon McCullum had confirmed after the conclusion of the second Test that Stokes would be back to captain the side at Trent Bridge. He and Atkinson were not considered for selection at The Oval, following a breach of team protocol after the victory in the first Test at Lord's a fortnight ago.
The ECB investigation has now concluded that Stokes was "not involved" and "did not witness" the nightclub incident that saw an England security liaison require medical treatment, and that Atkinson was a victim of "unprovoked attacks and did not retaliate". Separately, the Cricket Regulator found that there was no case for either player to answer.
"Stokes and Atkinson were found to have breached specific contractual obligations that require England players to at all times maintain the highest standards of conduct and act in the best interests of England cricket," an ECB statement said. "In addition to not being considered for selection for the second Rothesay Test, they have both been given a written warning as to their conduct.
"It was also concluded that no blame should be attached to the players for violent conduct at the nightclub. Stokes was not involved in the altercation and did not witness either incident. The evidence the ECB has seen demonstrates that Atkinson was the victim of unprovoked attacks and did not retaliate on either occasion."
England's squad for the deciding Test is the same as for Lord's but for Cox replacing Rew, with Jamie Smith returning from paternity leave after the birth of his second child and Ollie Robinson fit after "knee soreness" kept him out of the second Test. Having made five changes for The Oval, England could make exactly the same changes in reverse in Nottingham, with Stokes balancing the XI as allrounder and Shoaib Bashir the frontline spin option.
McCullum said that he hoped the team could approach the deciding third Test with a clean slate after a fraught couple of weeks that saw England playing an XI with three debutants and five players with one cap or fewer, and compounded by a sloppy performance that featured eight missed chances in the field.
"That's what we're anticipating and the conversations we will have will be about how we ensure we can reduce the noise as much as possible around the team and make sure the guys cross the line feeling very clear and calm about how they're going to execute their skills," he said.
"That's always a challenge and not because of the last week or so. That's always a challenge. It'll be no different from that point of view. But I envisage we get to Trent Bridge and start dreaming the dream of success rather than trying to get too caught up in things we haven't done quite so well."
