Cox, the Essex wicketkeeper-batter, is set to make his Test debut at some stage on England's tour to New Zealand which closely follows the West Indies tour and may leave the Caribbean early. He is likely to miss the five-match T20I series, and will arrive in New Zealand in time for England's warm-up match in Queenstown on the weekend of November 23, ahead of the first Test on November 27.

England said when they announced their squads that two Test players would be added and always planned to take Cox and Rehan to the Caribbean. They announced this week that Liam Livingstone will captain them in their three ODIs in the Caribbean, with Buttler missing that leg of the tour, and also added Essex's Michael Pepper to their squads as cover.

England ODI and T20I squads: Jos Buttler (captain, T20Is only), Rehan Ahmed, Jofra Archer, Jacob Bethell, Jafer Chohan, Jordan Cox, Sam Curran, Will Jacks, Liam Livingstone (ODI captain), Saqib Mahmood, Dan Mousley, Jamie Overton, Adil Rashid, Phil Salt, Reece Topley, John Turner.
