Ashes 2013-14: Stuart Broad unconcerned by Ashes sledging
England bowler Stuart Broad says there was no "line crossed" with on-field verbal exchanges during the first Ashes Test, but that mistakes may have been made with remarks made elsewhere.
Players from both sides will be spoken to by the ICC match referee before the second Test in Adelaide after a bad-tempered opening match.
Australia captain Michael Clarke was fined for using an obscenity to England's James Anderson during the first Test in Brisbane.
Broad also says the England squad are "heartbroken" at the departure from the tour of batsman Jonathan Trott, who has returned to England because of a long-standing stress-related condition.
