"I don't want to say at this stage until I've talked to Glamorgan about what's happening, so I haven't got any comment at the moment," he said.
Chappell, whose contract as coach of South Australia runs out in March, was offered the option of a two or three-year coaching position at Glamorgan.
The offer came after the South Africa captain, Hansie Cronje, withdrew from an agreement to replace Duncan Fletcher as coach last month. Fletcher had been released from his contract to take over coaching the England team.
The Australian Cricket Board has instructed staff at Test matches to limit the number of times they replay controversial incidents on giant television screens in an effort to stop the public humiliation of umpires. The board said it would restrict the number of replays to one in slow- motion and one at normal speed.
The move was made after John Reid, the match referee at last week's second Test between Australia and Pakistan in Hobart, complained that several controversial incidents were replayed repeatedly.
Reid said the replays incited crowds and put unnecessary pressure on umpires. He was particularly concerned by the repeated showing of Justin Langer's controversial edge behind off the Pakistan fast bowler Wasim Akram on the final day.
Although Langer was given not out by the Australian umpire Peter Parker, the large screen repeatedly showed a "snickometer" reading indicating he had hit the ball.
The snickometer detects sound at the precise moment the ball passes the bat, but it has been heavily criticised by players. Langer, whose second innings knock of 127 helped to guide Australia to victory, has denied hitting the ball.Reuse content
