Heartbreaking to lose Trott - Broad

Broad unconcerned by Ashes sledging

England bowler Stuart Broad says the gruelling schedules players face may have exacerbated the problem that led to Jonathan Trott's "heartbreaking" early Ashes exit.

Batsman Trott, 32, has flown back to the UK from Australia because of a long-standing stress-related condition.

"We can do 270 or 280 nights a year in hotel rooms, which can get quite hard," Broad told BBC Radio 5 live.

"The most important thing is that players recover and get right again."

Broad, 27, admits the rest of England's players have been left "heartbroken" by his departure and says they were not aware of the extent of the Warwickshire batsman's problems.

"It's heartbreaking for us to lose Trotty. He's been part of the side for four or five years - he's a fantastic guy. He gave us a lot of solidity in the number three spot," Broad said.

"I don't suppose as a squad we were overly aware of the troubles he had.

"But it all turns to making sure he gets right now. The important thing is he's got the support of the changing room he's played with for 49 Tests."

No timescale has been suggested for when Trott, who scored 19 runs in two innings during England's 381-run first Test defeat in Brisbane, will play cricket again.

Australia fast bowler Mitchell Johnson, who twice dismissed Trott in Brisbane, expressed sympathy for the South African-born batsman's situation, having battled his own problems.

The 32-year-old contemplated retirement in 2011 after a slump in form left him feeling mentally drained, but looked back to his best against England in the first Test.

"It was a real shock for me. It can be tough at times when it's not going so well," Johnson said.

"You start to think about every little thing that's going on in your life when you should be focusing on one thing. It seems maybe he's thinking that way at the moment, and just needs to just get away from the game.

"I just wish Trott the best. Hopefully he can come back later in the tour or in the future, because he's a great player for England and he's done exceptionally well."

Meanwhile, players from both sides will be asked to calm down by the ICC match referee before the second Test in Adelaide which starts on 5 December after a bad-tempered opening match.

Australia captain Michael Clarke was fined for using an obscenity to England tail-ender James Anderson and opener David Warner was also criticised for being "disrespectful" by England captain Alastair Cook for remarks about Trott's "weak" second-innings dismissal.
