Australia have drafted in pace pair Peter George and Doug Bollinger as replacements for Ryan Harris for the Test and Twenty20 series against Pakistan in England.
Harris suffered a knee injury in the final one-day international against England and Cricket Australia have now brought in South Australia paceman George for the Tests against Pakistan while Bollinger will bolster the 20-over squad.
Australia's chairman of selectors Andrew Hilditch said: "The unfortunate knee injury to Ryan Harris has seen him ruled out of the Twenty20 internationals and the Test tour against Pakistan in England.
"Doug Bollinger has been added to the Twenty20 squad and Peter George has been called into the Australian Test squad.
"Peter George had an excellent Shield season last year and was called up to the New Zealand tour earlier in the year where he impressed around the squad.
" He has followed that with a very impressive bowling performance for Australia A against Sri Lanka A recently and we are confident he will perform well at international level should he get the opportunity on this tour."
Bollinger is already in England having played in the recently-concluded ODI series against England, while George will leave Australia for England on Monday evening.
Left-arm pace bowler Mitchell Johnson returns to the Australia side for the opening Twenty20 at Edgbaston having missed the NatWest Series with an elbow infection.
His absence gave fellow quicks Shaun Tait and Josh Hazlewood a chance to impress against England, the former playing a key part in the tourists' back-to-back wins at the Brit Oval and Lord's.
And Johnson believes the way in which Ricky Ponting's bowling attack remained competitive despite depleted resources is a positive sign.
He said: "We've got a good bunch that have been able to rotate in and out of the side, whether it's an injury or not, they've been able to rotate very well.
"Maybe it's taken one game to gel back as a group again, but looking for the future we have a pretty good squad at the moment.
"Losing a player, another player can come back in like Ben Hilfenhaus. Josh Hazlewood had a crack this one-day series and it just shows the depth we have in Australian cricket.
"There's always been talk about the McGrath-Warne era. I think we've really started to make a stamp on how we perform as a group.
"We're not trying to go out there and be those guys, we're just trying to do the best we can and play good cricket for Australia and win games. We don't look to be intimidated by those big names before us.
"We've just got to go out there and make a name for ourselves and I think we're doing a really good job at the moment."
