The Pakistan Cricket Board (PCB) has appointed former Test bowler Sarfraz Nawaz to work with Shabbir after he was suspended from bowling in international cricket last month by the International Cricket Council (ICC) for having an illegal action.

The ICC has formed a bowling review group to hear out Shabbir's appeal in Dubai on January 21, with former Indian pace bowler Javagal Srinath the only Test bowler on the panel.

"We have nearly completed a 30-minute video having footage of Shabbir's revised action after the work done on him by Sarfraz in the past two weeks," PCB director Saleem Altaf told Reuters.

"We are confident we can get the ban lifted or reduced on the basis of what the improvement we have seen in his action now," Altaf said.

Altaf will accompany Shabbir to the ICC hearing.

The 29-year-old is the first bowler to receive a 12-month suspension after his action was reported twice in 2005.

The ICC group will watch video evidence from the Multan Test against England in November after which Shabbir was reported again and will also hear reports from match officials.

The rangy six-foot-five seamer returned to face England later in the year but was reported for the second time in Multan in November.

Shabbir played 10 Tests and 32 one-day internationals, with best figures of 5-48.
