Inzamam again succumbed to a back injury while Razzaq has not recovered from an illness which laid him low during the second Melbourne Test, which Pakistan lost by nine wickets to lose the three-match series.

Stand-in skipper Yousuf Youhana said the setbacks had forced a delay in the composition of the Pakistan team, with all-rounder Shoaib Malik and paceman Mohammad Sami already ruled out with injuries from the Melbourne Test.

"We can't even name a team yet," Youhana said Saturday. "We have to replace four players. There will be a lot of changes."

There were hopes that Inzamam, the most experienced player in the touring side, would help ease the player shortage but he failed to come through a practice session at the nets at the Sydney Cricket Ground on Saturday, leaving the tourists in further disarray.

Razzaq was hospitalised twice in Melbourne after complaining of dizziness and shortness of breath.

Although he batted in Pakistan's second innings he was taken back to hospital after the Melbourne Test after collapsing.

Sami has been ordered to rest because of a foot injury while Malik split the webbing on his fingers taking a catch in Melbourne.

Youhana said his team was up against it in the final match of the series after going down to Australia inside four days in both the Perth and Melbourne Tests.

"Australia don't take it lightly and we don't either," he said.

"I know they're better than us because we have a lot of young and inexperienced players but we're still trying to win this game."

Meanwhile, Australian selectors sprung a surprise Saturday by axing Michael Kasprowicz and Darren Lehmann and bringing Shane Watson and Stuart MacGill into the Australian team for the final Test at the Sydney Cricket Ground.

Kasprowicz, who has been one of Australia's best bowlers over the last six months, was named 12th man while the Test career of Lehmann, who turns 35 soon, could be over after a poor sequence of scores.

Reports said that captain Ricky Ponting debated the team's make-up with selector Allan Border before and during training before announcing to the media the sacking of Kasprowicz and Lehmann despite Australia's 2-0 unassailable series lead over Pakistan.

"We think it's the best balanced side for this opposition and these conditions," Ponting told his match-eve media conference.

Asked if his dumping signalled the end of Lehmann's Test days, Ponting said: "No way at all. His selection was made wholly and solely for this game and these conditions."

Ponting said it was opportune to give 23-year-old Watson, a fast bowler and accomplished batsman, his Test debut.

"We've all known Shane's potential for a long time now," he said.

Ponting said MacGill's selection for his 34th Test was in response to curator Tom Parker's pitch looking like "the SCG of old".

The pitch was expected to provide significant turn over the final three days when MacGill and Shane Warne will bowl in tandem.

"They're two of the best in the world," Ponting said. "Stuey knows conditions here like the back of his hand and his record here is absolutely outstanding and Warney's isn't much different.

"It's a great prospect to have them both in the side. Stuart really deserves his opportunity ... his form has been outstanding.

"Pakistan have never been great players of leg-spin bowling. We think as this game goes on, having those two absolute quality leg-spinners in the side is going to be the hardest bowling for Pakistan to face. It should be exciting to watch."

Ponting said breaking the news to Kasprowicz and Lehmann was the worst part of his job.
