The Australian fast bowler Mitchell Johnson says he understands why he's been dropped from the team to play in the second Ashes cricket test starting this afternoon in Adelaide.
Johnson was out of form with both the bat and ball in the drawn first Test in Brisbane, finishing with match figures of none for 170, dropping a catch and making a 19-ball duck.
Johnson concedes a lack of wickets in the first test counted against him he's just going to have to work very hard in the nets.
Australia's eleven won't be known until just before play starts.
