Batty brought in as back-up for Giles

The Worcestershire offspinner, Gareth Batty, has been called into England's squad ahead of the first Test against Bangladesh, as cover for Ashley Giles, who has a hip injury.

Batty, 27, played the last of his five Tests in Antigua in April 2004, at the end of England's triumphant tour of the Caribbean. But he toured South Africa last winter with both the Tests and the one-day sides, and has been in good form for Worcestershire in the County Championship. In their current match against Essex at Chelmsford, he has made 54 and taken 3 for 26.

Giles, meanwhile, has been troubled by a hip problem since Warwickshire's Championship match against Sussex at Hove on May 10. "Ashley's fitness will be re-assessed by the England medical team tomorrow when the Test squad reports for practice," said David Graveney, England's chairman of selectors. "Gareth has been added to the squad as a precautionary measure."

Giles was restricted to 11 overs in the match against Sussex but batted in both innings and was confident of making the Test side. However, he is now feeling discomfort again and will be put through his paces by England's medical team on Monday. He began the season in superb form, taking 24 wickets at 18 apiece, including three five-wicket hauls.

Giles's injury could increase the chances of England playing a full hand of seamers at Lord's. Simon Jones has bowled 34 overs for Glamorgan in their game against Hampshire, to suggest that he has recovered from his back injury. The vulnerability of the Bangladesh batting to the county seamers they have faced may encourage the selectors to pick an all-pace attack, therefore giving Jon Lewis a Test debut and reducing the workload on Andrew Flintoff.

Duncan Fletcher has said that England will need to make sure they do not take Bangladesh lightly at Lord's. He believes Bangladesh have the ability to make things awkward if England are not on top of their game.

He told BBC Sport: "They are a side that will make some progress. Cricket is a strange game and you can never underestimate anyone. It's important we appreciate there are some good players in their side. There have been other sides who have been in the same position when they've entered the international arena and look where they are today. On any given day if one or two of their bowlers bowl in the right areas, you've got to make sure you're at the top of your game."
