Arthur: Warner spot in danger

Australia coach Micky Arthur admits David Warner's batting position for the first first Ashes Test is now jeopardy following his behaviour last weekend.

The opener was fined and suspended until the start of the Ashes for an incident in which he admitted to punching England batsman Joe Root in a Birmingham bar.

He will miss the rest of Australia's involvement in the tournament and their two warm-up matches before he is again available for the first Test against England at Trent Bridge, which starts on July 10.

And Arthur says Warner's suspension could cost him his position, with Ed Cowan, Chris Rogers and Shane Watson all competing for a place at the top of the order.

"I guess it's a real opportunity for the other batsmen in the squad to stand up in the first two practice games because if they do that they've got a real good chance of starting that first Test match," Arthur told Sky Sports News.

Asked if it's unlikely that Warner will start in the first Test match, Arthur said: "That's hypothetical. Who knows what will happen down the line, but we've just got to keep him going and keep him ready in case anything happens.

"We've got to have him best prepared to go and then we'll sit down and select when the time comes.

"I certainly think he has (moved on). He's learned a big lesson and a lesson that will hopefully work in the right way for him and we've all put it behind us now and the squad is totally focused on the cricket and we all are.

"That's what we're here for. We're here to have a big English summer and nothing will deter us from that."
