X-rays have revealed that Bangladesh captain Mushfiqur Rahim has sprained his right ring finger on the second day of the first Test against Pakistan. Imrul Kayes kept wicket in his place from the final drinks break till stumps.

"The X-rays didn't show anything serious like a fracture," Bangladesh media manager Rabeed Imam said. "He will now be taking medicine and applying ice. Whether he will take the field on the third day will depend on how the pain is managed tonight."

The incident occurred in the 35th over when Azhar Ali edged debutant seamer Mohammad Shahid. Mushfiqur dived full length to his right but the ball struck low on his hand and popped out, giving the batsman a third life. Immediately afterwards though, Mushfiqur needed medical attention from Bangladesh physio Bayjedul Islam.

Mushfiqur kept wicket for another eleven balls before he left for the dressing room at 3.55pm as the drinks trolley rolled out. Tamim Iqbal, the vice-captain, led the side till the end of the day's play.
