England fast bowler Ajmal Shahzad has been ruled out of the opening Test against Pakistan with an ankle injury and replaced in the 12-man squad by Yorkshire team-mate Tim Bresnan.
"After twisting his left ankle with Yorkshire over a week ago Ajmal went on to successfully play in a Clydesdale Bank 40 match for his county last Monday," ECB Chief Medical Officer Nick Pierce said in a statement.
"Unfortunately Ajmal felt some discomfort following England practice at the NCPC on Tuesday and as a precautionary measure it is felt he is best to undergo rehabilitation on the ankle for the remainder of this week.
"We expect Ajmal to make a full recovery, he hasn't been ruled unavailable for the 2nd npower Test starting next week. He will continue to be assessed this week before a decision on his fitness is made."
Shahzad made his debut in the second Test against Bangladesh earlier in the summer and his replacement Bresnan, has played five Tests since making his debut against the West Indies last year.
Trent Bridge hosts the first of four matches, which gets underway tomorrow (29th February).
