This game will be remembered more, however, for the sight of a highly-skilled, highly-experienced batsman clutching his head after ducking into a short-ball from Boyd Rankin. In truth, Solanki did not play the delivery terribly well, turning his head on the ball, and taking the blow just below the ear in an area unprotected by his helmet. The ball may well not have misbehaved, either, but Solanki was, understandably, reluctant to trust the capricious pitch and failed to commit to the shot he might have played in other circumstances. Thankfully, X-rays showed no serious injury and Solanki returned to the ground in the evening. He should be able to bat on the final day.
