More withdrawals for PM\'s XIII

The Prime Minister's XIII to play Papua New Guinea on Sunday has been hit with more withdrawals after Brisbane's Tonie Carroll and Steve Michaels pulled out of the match.

Carroll will undergo immediate surgery on his troubled shoulder and is also out of contention for next month's Test match against New Zealand, while Michaels has a chest infection.

South Sydney forward Dean Widders and Gold Coast centre Brett Delaney have been called into the squad as replacements. Six players have now withdrawn from the original side named last week.
