Trescothick made his comeback on Saturday in the C&G Trophy final after six weeks on the sidelines with a broken thumb.

Irani underwent knee surgery last month and will make his comeback in Sunday's Norwich Union League match with Lancashire.

Dominic Cork is also struggling with a finger injury and all three players will test their fitness with outings for their counties before the 14-man squad assemble at The Oval on Tuesday.

Chairman of selectors David Graveney said: "We want to give these three players some more match practice before the Test match and we should have a clearer picture of their fitness by Tuesday.

"Although we are aware of the limited match practice Ronnie has had recently, he was out for only a couple of weeks through injury and was able to practice with both ball and bat on Friday and Saturday of this week.

"Marcus Trescothick played yesterday in the C&G final and suffered no reaction above the norm to his thumb injury. He was happy with the way he batted and felt fine in the field."

As for the team, Graveney said: "The selectors discussed the likely shape of the team when we met earlier in the week and we were not inclined to play seven batsmen and four bowlers.

"This policy did not work for us against Sri Lanka at Lord's earlier in the summer and we feel that we will need a five-bowler combination for this Test.

"At this stage without having seen the wicket, we are not expecting a surface which is especially helpful to spin and as a consequence we have decided not to include a second specialist spinner in the squad."
