London: England named an unchanged squad on Sunday for the fourth test against India starting on Thursday at The Oval.
England became the top-ranked test nation when they displaced India following Saturday`s win in the third test at Egbaston which secured a 3-0 lead in the series.
"Batsman Jonathan Trott is making steady progress in his rehabilitation from his ongoing shoulder injury but he requires further treatment and won`t be fit for the fourth and final test match. As such Ravi Bopara retains his place in the squad," England National Selector Geoff Miller said in a statement.
Bowler Chris Tremlett is available for selection following continued treatment for his back injury and he and Steven Finn are included in a broader 13-man squad for the last Test match of the English summer.
Bopara failed again with the bat in Birmingham while Tim Bresnan excelled with the ball in Tremlett`s absence.
