Sydney - Former Australia vice-captain David Warner has conceded he may never play for his country again after being banned for 12 months.

Warner apologised in tears on Saturday for his role in ball-tampering but said he may appeal his 12-month ban in the latest emotional public appearance over the scandal.
A sobbing Warner said he realised he may never play for his country again. But he stonewalled questions about who was aware of the plot and whether it was the first such incident within the team.
Warner, 31, told a media conference in Sydney: "I can honestly say I have only wanted to bring glory to my country through playing cricket.
"In striving to do so I have made the decision which has had the opposite effect and it's one that I will regret for as long as I live."
Warner's appearance comes after similar heartfelt apologies by opening batsman Cameron Bancroft and captain Steve Smith, who broke down when he faced the media on Thursday.
Coach Darren Lehmann, convinced to step down after seeing the apologies from Bancroft and Smith, was also tearful as he announced his resignation.
Smith and Warner were banned from international and domestic cricket for a year and Bancroft was suspended for nine months after the incident during the third Test in Cape Town.
Bancroft was caught on camera trying to use yellow sandpaper to alter the ball, an offence which triggered an outpouring of criticism against the hard-nosed Australian team.
Warner, who has played 74 Test since his debut in 2011, said he would be seeking ways to make character changes. Warner, who has been described as the team's "attack dog", was also banned in 2013 after punching England's Joe Root in a bar.
"I suppose there is a tiny ray of hope that I may one day be given the privilege of playing for my country again, but I am resigned to the fact that may never happen," he said.
"But in the coming weeks and months I am going to look at what has happened and who I am as a man.
"To be honest, I am not sure right now how I will do this, I will seek out advice and expertise to make serious changes."
Warner called it a "horrible" decision, adding: "I failed in my responsibilities as vice-captain of the Australian cricket team."
The fallout from the crisis has seen Warner dumped by sponsors ASICS and LG. Along with Smith, he has also been ejected from this year's Indian Premier League, losing contracts worth nearly $2 million each.
