moeen ali is to undergo a scan on friday after suffering soreness in his left side which meant he missed england’s practice session in perth on thursday.
the worcestershire all-rounder will not feature in england’s opening two-day warm-up game against a western australia x1 at the waca starting on saturday.
england have two more warm-up matches before the first ashes test in three weeks time.
moeen, who last week signed a new five year contract at New Road, has enjoyed a superb 2017 for his country in test cricket.
he is the 10th highest wicket-taker this year with 30 victims in seven tests at an average of 21.30.
two of worcestershire’s 2017 overseas players are in the top five of test wicket-takers during this calendar year.
australian spinner nathan lyon, who played four specsavers county championship matches as a replacement for john hastings, has amassed 46 wickets in seven tests.
but not far behind is indian all-rounder ravichandran ashwin who played in the final four championship games of the summer.
he has picked up 44 wickets in eight tests.
