Jon Holland, the left-arm spinner, has been ruled out of Victoria's JLT One-Day Cup opener because of a precautionary knee surgery due to "wear and tear."
He will be sidelined for up to a month. The vacancy created by Holland's injury will be filled by Fawad Ahmed, the legspinner.
Holland, who played two Tests on the tour of Sri Lanka last year, reported discomfort in his right knee more than a week ago. The injury flared up in Perth during Victoria's first net session, leading to a "minor surgery" on Wednesday.
"Jon reported some discomfort in his right knee following training last week. Initial scans proved inconclusive but Jon continued to feel some discomfort while bowling in Perth and we decided surgery would be the best option ahead of the season," said Nick Adcock, Cricket Victoria's Sports Science and Sports Medicine manager.
"The surgery on his right knee was successful, and we're hopeful Jon can return to training after two-four weeks recovery."
Ahmed is the second injury replacement for Victoria in this tournament. Earlier in the week, Xavier Crone was called in to the squad after fast bowler John Hastings injured his back at training.
