SOMERSET have admitted their fitness programme is under review after wicketkeeper batsman Craig Kieswetter was ruled out of this week's crucial Championship game against Durham with an ankle injury suffered playing football football.

Kieswetter, who has been in excellent form, damaged ankle ligaments last Friday during a football match between the players in the indoor nets at Trent Bridge during a rain-affected match against Nottinghamshire.

Somerset's director of cricket Brian Rose told the club's official website: "All clubs do it and you can get an injury from stepping on a cricket ball in the nets.

"It is just bad luck, but we will be looking at whether football is a risk because we don't want to lose another player through it."

Kieswetter's place will be taken by Carl Gazzard for the top of the table clash against Durham at the County Ground, which starts tomorrow (Tuesday).

Rose admitted losing Kieswetter was a blow: He said: "Craig has not broken any bones, but there is some ligament damage.

"We will know more in a few days and hopefully he won't be out of action for too long. But he will not be able to face Durham which is disappointing.

"Carl Gazzard has had a good season in the 2nd XI and will come into the side.

"But Craig is in great form with the bat at the moment so it is a blow."

Following their rain-affected draw against Notts - no play was possible on the final two days - Somerset are second in the table, four points behind Notts, who have played a game more.

Durham are seven points behind Somerset, having played the same number of games.
