Pakistan all-rounder Abdul Razzaq is likely to undergo an MRI scan for his back injury.
According to Associated Press report, Pakistan team manager Yawar Saeed expects that Razzaq "will need the MRI so we can see what the problem is."
Razzaq is a key member of Pakistan squad with his absence, the troubled Pakistan team is bound to struggle. He has already missed two one-day internationals against England so far, including the four-wicket defeat on Sunday at Headingley. Pakistan trails 2-0 in the five-match series.
"Our physio Dale Naylor will assess him once again tomorrow (Monday) and decide if we need to send him for an MRI," Saeed said.
Pakistan has had a very difficult tour of England so far, surrounded by spot-fixing allegations that led to three players — Salman Butt, Mohamamd Asif and Mohammad Aamer — being suspended and sent home.
Apart from Razzaq's injury, replacement Mohammad Irfan has suffered with cramp in his two matches so far.
Captain Shahid Afridi criticised Irfan after Sunday's game but his bowling options are limited. Another pace bowler, Wahab Riaz, is also to be questioned by police and has not played since this was announced.
