GWENT'S Darren Campbell (pictured above) is the latest Gwent sprint injury concern following the scare suffered by Newport's Christian Malcolm (above right). Campbell has given Britain's athletics team a fright after revealing he has a slight hamstring tear.

The Olympics 200m silver medallist in Sydney four years ago woke up yesterday suffering with what he thought was cramp.

However, after having a scan the results showed a slight muscle tear.

Campbell, 30, is due to line up in the 100 metres heats tomorrow and is one of Britain's outside hopes of medal, particularly with Greek reigning champion Kostas Kenteris having been ruled out following a drugs scandal last week.

"I'm told it should be okay," said Campbell, who has suffered with hamstring problems since the Sydney Olympics.

"I'll know more over the coming hours but I'll be saying a few prayers tonight."

Campbell's injury is the second blow to team GB in just 24 hours after it was revealed yesterday that Malcolm had spent five days in hospital suffering from acute kidney failure, contracted from a suspected virus.

Malcolm, 25, was released from hospital on Sunday and has resumed light training ahead of his first 200 metres qualifying heat, which is on Tuesday.

However, for Campbell the situation is looking even more critical as he is due to compete tomorrow in the 100m heat.

A spokesman for the British athletics team confirmed that Campbell had an MRI scan yesterday which revealed a small tear in the hamstring of his right leg.

He is having injections in a bid to heal the muscles in his leg but it will be touch and go whether he can compete.

One option for Campbell might be to pull out of the 100m event and focus purely on the 200m, giving himself another three days to recover from the injury.

Meanwhile Malcolm is said to be training well after his release from hospital.

He was described by a team GB spokesman as "one of the hardest trainers on the side" and officials are delighted with his progress.
