Shoaib could not complete his 22nd over after he injured the wrist on his left hand while Kamal hurt his elbow. However, Shoaib is expected to bowl on Thursday, the injury being only external.
Shoaib, the pick of the home side bowlers with figures of 3 for 37, fell on the follow-through in his 22nd over, hurting the wrist in his left hand.
Although he bowled one more over with a bandaged wrist, he left the field subsequently before returning 40 minutes later. However, umpire David Shepherd told the bowler he could not resume bowling straightaway as he was out of the ground for a long time and the day's proceedings were coming to an end.
Kamal, fielding at forward short-leg, was hurt by a pull shot of Indian skipper Sourav Ganguly in the post-tea session. He had X-rays taken on his injured elbow later.
The fresh injuries have added to the woes of Pakistan, already without Lahore Test hero Umar Gul, paceman Shabbir Ahmed, wicketkeeper Moin Khan and all-rounder Abdul Razzaq.
