England's Magellan Ashes tour has been rocked with two key players going down with injury in the team's second net session at Richardson Park in Perth.
England's spin bowling allrounder Moeen Ali is in doubt with a side injury and played no part in today's training session, while fast bowler Steven Finn suffered a knock to his left knee batting in the team's net session.
Finn was reported to have crouched to the ground in pain after taking the blow, and limped off gingerly to the change rooms.
It's understood both will be having scans in Perth on Friday, and both have been ruled out of this weekend's tour-opening two-day match against a Western Australia XI at the WACA.
Blows to two key frontline players would be a serious concern for England who are taking a conservative approach to treatment, with more to be known about the extent of their injuries after Friday's scans.
Finn was only added to England's Ashes touring party following the indefinite suspension of Test vice-captain Ben Stokes following his alleged involved in a wild street brawl in the early hours after an England limited-overs match.
Moeen has played 44 Tests for England and looms as a key player in the middle order. He averages 34.66 with the bat, with five Test centuries and 12 fifites to his name, and also has 128 Test wickets at 37.32.
Meanwhile, 30-year-old late bloomer Mark Stoneman hopes he is the answer to England's revolving door problem at the top of the order.
Alastair Cook has had 12 opening partners since Andrew Strauss' 2012 retirement, with Stoneman being the most recent.
Stoneman, who debuted during in August's three-Test series against the West Indies, is again set to partner Cook at the top of the order for the Ashes opener, starting on November 23 in Brisbane.
He said being picked for the Ashes was the pinnacle for him in Test cricket, and would prove to be his toughest challenge.
"I think I've got a natural flow to my game, and I'm always looking to score," Stoneman said.
"Hopefully, that can take pressure off Cookie if I'm playing well.
"I don't think it rests just on myself and Cookie at the top of the order but, generally, the momentum will start there."
Stoneman paid tribute to former Australian batsman Michael Di Venuto for helping him to propel his career into the Test arena.
The pair formed a close relationship while playing together at English county side Durham.
Stoneman switched to Surrey in 2016 after Di Venuto was appointed head coach there.
"He's been a fantastic mentor for me," Stoneman said.
"He doesn't complicate the game too much. He's definitely taken my game forward."
Stoneman, whose wife is Australian, spent six seasons playing grade cricket in Sydney, giving him good experience of the conditions he can expect this summer.
