Amjad and Bopara cover for Flintoff

Kent seamer Amjad Khan has been added to England's squad in the West Indies

England have called up Kent seamer Amjad Khan and Essex all-rounder Ravi Bopara as cover for the injured Andrew Flintoff in the West Indies.

Amjad and Bopara had been with the England Lions squad in New Zealand but will now travel to the Caribbean.

Flintoff, 31, has been struggling with a hip problem during the current third Test in Antigua and will undergo a scan tomorrow.

Flintoff has a suspected muscle tear in his right hip but has not been ruled out of bowling today if required in England’s bid to level the series.

Uncapped Amjad, 28, who was born in Denmark, was last involved in the England squad in India before Christmas, when he replaced the injured Ryan Sidebottom.

Bopara, 23, last played for England in the one-day series against India. His last Test was against Sri Lanka at Galle in December 2007.

“They are coming because Fred (Flintoff) has hurt himself and will be here as soon as possible,” said assistant coach Andy Flower.

“People will have seen yesterday that he cannot move properly because of some problem in his hip.

“There is a limit to how much we know about the injury at this stage but he is going to give bowling a go.

“He is struggling to get it through at full pace but if we need him he will bowl.”

Ravi Bopara last played for England in the one-day series against India last November

With back to back Tests in Barbados and Trinidad starting next Thursday, however, Flintoff's latest injury setback is a blow to England's hopes of overturning their current series deficit.

He only began the campaign after passing a fitness test on a left side strain.

"He knows his body very well and he will feel whether he can do the job," added Flower.

"Even at three-quarter pace he can still do a job for us. But it's finding a balance between winning the Test and not doing any lasting damage.

"We don't know what the injury is at this stage and an MRI scan will give us more information.

"The medical guys think there might be a little tear there, they're not sure, but it is a muscle problem in his hip."

Flintoff only returned from a long-term ankle injury for the second Test of four against South Africa last summer.

“Fred works really hard at his fitness but I think through workload and wear and tear over the years he keeps picking up these little injuries,” said Flower.

“He is a strong bloke both physically and mentally and he will get himself right hopefully.”

Kent coach Simon Willis was delighted with Amjad’s call-up. He said: “This is great news for both Amjad and Kent County Cricket Club.

“He has looked sharp in the nets and is in good physical shape. He totally deserves his call up and I am confident that he will do well.”
