Dubai: South Africa will hope ace paceman Dale Steyn will recover in time for the second Test against Pakistan starting on Wednesday to help them level the series.
Steyn, 30, had to cut short his training session on Sunday and did not train on Monday as he was seen working with South African physiotherapist Brandon Jackson.
Team manager Mohammed Moosajee said Steyn will be monitored.
"We should have a better idea of the situation tomorrow," Moosajee, South Africa's team manager told ESPNcricinfo. "We need a 24-hour period before we can determine exactly what's wrong."
South Africa's vice captain AB de Villiers also confirmed Steyn's fitness problems.
"He (Steyn) did tweak something in the fielding practice yesterday, but we think it's not too serious, so we are just taking a good precaution and making sure he will be ready for the second test match," said De Villiers on Monday.
Steyn, ranked number one bowler in Test rankings, took 3-88 in Pakistan's first innings of the Abu Dhabi Test and then grabbed one more in the second when Pakistan needed just 40 for the win.
South Africa will also likely to miss first Test centurion Hashim Amla who returned home last week to be with his wife for the birth of their second child.
