Uncapped Sussex trio Phil Salt, Laurie Evans and Ollie Robinson have been called up for England training.

They join county colleagues Chris Jordan and Jofra Archer in a bumper 55-man group who are aiming for a possible intensive international summer.

The expanded group will not be brought together in one place, with individual sessions at a host of county venues including Hove the only form of training currently approved.

It does not represent an official England squad.

Format-specific squads will be named at a later date, starting with Test cricket.

Hopes are high that the delayed three-match series against the West Indies will go ahead in July but should the rest of the calendar fall into place - including a full Pakistan tour and limited-overs matches against Australia and Ireland - a wide pool of players will be required.

ECB performance director Mo Bobat, who joined the selectors and the head coach Chris Silverwood in putting together the list, said: “It’s really pleasing to be in a position to have players returning to training and a huge amount of work has been done by many to get us this far.

“The pool of players will give selectors strong options when it comes to selecting squads across formats further down the line, as we move closer to our aim of playing international cricket this summer.

Salt, pictured, was called into the England Twenty20 squad last year but did not make the final line-up.

As well as his hard-hitting feats with Sussex, he has also picked up short-format experience around the world on the T20 circuit.

Seamer Robinson has flourished under the guidance of Jason Gillespie, taking 137 Championship wickets over the last two seasons, and impressed with England Lions over the winter.

Evans, 32, has become known as a T20 specialist in recent years. A Lions knock of 94 against Australia A in February might have sealed his selection.
