Australia have bolstered their pace bowling options ahead of the second Ashes cricket Test in Adelaide following the drawn opener with England in Brisbane.
England racked up an incredible 517 for 1 in their second innings to save the first Test, with none of Australia's front-line bowlers taking a wicket.
Ryan Harris and Doug Bollinger have now been added to the eleven that played at the Gabba in a 13-man squad.
Mitchell Johnson, who returned none for 170, would appear most under pressure.
The left-arm seamer has taken 166 Test wickets but only 11 in his last five Tests - and five of those came in one innings against India at Mohali in October.
the second test starts on Friday.
