Australia batsman Shaun Marsh has been ruled out of the remainder of the one-day series against Sri Lanka after injuring his lower back in Wednesday's opening defeat, Cricket Australia said on Thursday.
Promising middle order batsman Callum Ferguson will join the squad in place of lefthander Marsh for the final two matches against Sri Lanka -- in Sydney on Friday and Brisbane on Sunday.
"It's an unfortunate injury for Shaun," chairman of selectors Andrew Hilditch said in a news release.
"However, it does create another opportunity for Callum Ferguson to come back into the Australian one-day team and press his claims."
Australia have lost their last six matches in all forms of cricket and are desperate to return to winning ways before the Ashes test series against England begins in Brisbane on Nov 25.
