Wahab Riaz must prove his fitness after a hand injury to feature in Pakistan's Twenty20 squad to face Sri Lanka.
Pakistan will give Wahab Riaz time to prove his fitness for two Twenty20 contests against Sri Lanka, while Umar Akmal returns after being dropped for the one-day series.
Fast bowler Wahab suffered a hairline fracture to his knuckle during the Test series between the sides last month, which Pakistan won 2-1.
The injury has kept him out of an ongoing five-match ODI rubber - which Pakistan lead 2-1 - but he has been provisionally named in the T20 squad, with Ziaul Haq ready to come in should he not make it.
"Wahab Riaz is expected to start bowling from July 24 after recovering from a hand injury sustained during the Test series against Sri Lanka, under the supervision of NCA [National Cricket Academy] coaches, and would be included in the squad upon clearance that he is injury free and bowling to their satisfaction," chief selector Haroon Rashid said in a statement from the Pakistan Cricket Board.
"Otherwise Ziaul Haq - a budding young fast bowler having toured recently with Pakistan A - will take his place in the team."
Umar is included in the squad after he was overlooked for the ODI series because he failed to report for a training camp at the National Cricket Academy in Lahore ahead of the contests.
Yasir Shah, Mohammad Irfan and Sohail Tanvir have all been recalled to the T20 set-up, but Haris Sohail (knee) and Sohaib Maqsood (hand) miss out as they continue their rehabilitation from injury.
The first T20 contest takes place in Colombo on July 30.
