Lees, 28, captained the Lions squad in Australia and has shown great potential in the County Championship over the past few years with Durham and previously Yorkshire. He scored 625 runs in last year’s Championship campaign, with the highest score of 129.
The 24-year-old Fisher took 20 wickets for Yorkshire last season at an average of 19.65 from County Championship matches. His control with the ball has impressed the England set-up for some time, and he was a stand-out performer for the Lions during the winter programme.
Alongside the new additions to the squad, the Lancashire duo of Saqib Mahmood and Matthew Parkinson will be aiming to make their Test debut in the Caribbean having featured in previous squads.
Surrey wicketkeeper Ben Foakes returns to the squad for the first time in under a year when he played the fourth Test in Ahmedabad last March against India.
