NATHAN CLARKE was a lingering injury worry for Town as they flew back into England today.

The 21-year-old centre-back suffered a left thigh strain during Town's 1-0 Copa de Ibiza tournament defeat to Coventry City.

He has been under intensive treatment from physio Lee Martin ever since but has not managed to shake off the problem.

"Nathan has a very tender left thigh," confirmed Martin today.

"While he can do all the stretching and bike work in the gym, it's hard to tell to what degree there is damage.

"Nathan doesn't feel too bad, so hopefully he will be able to get back into things quite quickly, but it will be a matter of assessing things over the next few days."

Martin believes Andy Booth (ankle), Andy Holdsworth (ankle) and Danny Adams (calf) will be fit to feature in next week's friendlies.

"They are all suffering some soreness, but it's not serious," said Martin.

"Boothy should be okay to start training next week and the other two are comfortable about how their injuries are coming along.

"The only worry, really, is Nathan, but we will see how he starts the week and take things from there."

Town have trained on the SD Portmany pitch in San Antonio and have varied their schedules with swimming sessions in the sea.

"It's been a really good week for the lads, they have worked really hard" added Martin.

Meanwhile, Town's Under 15 keeper Alex Smithies has been selected for the England Under 16 squad to face Iceland.
