He was taken to hospital for an X-ray and then returned to Edgbaston to receive further ice treatment on the injury.

England plan to re-assess Trescothick's condition on Friday and no decision has yet been made about whether he is fit enough to bat in the Test, but as a precaution he has already been ruled out of fielding again during South Africa's innings.

Trescothick will be allowed to take his place as opener if he is regarded as fit enough to bat because under the International Cricket Council's playing conditions for Test matches, he does not have to make up the time he is absent from the field as his injury is regarded as external.
