Victoria's captain Matthew Wade faces a period on the sidelines after suffering a fractured collarbone while batting in the nets before play on the first morning of the Sheffield Shield match against Western Australia at the MCG.

Cricket Victoria confirmed that Wade had gone for scans immediately, which confirmed the injury, and the match referee Bob Stratford had approved a late change to Victoria's team, with rookie wicketkeeper Aaron Ayre called in to make his first-class debut.

"Matt will get further medical advice on Monday to determine the extent of the injury and recovery period," Victoria's physiotherapist Nick Adcock said.

Wade's injury comes at a time when he was hoping to have a strong start to the Shield season, with Peter Nevill currently occupying the Test wicketkeeping place but far from a permanent fixture in the side yet. Wade has played 12 Tests and scored two centuries, and while he is the incumbent ODI and T20 wicketkeeper for Australia, he hopes to add to his Test tally.

"I feel like if I string a few good games together I'm definitely up for selection," Wade said on SEN radio on Friday. "I had a good chat with [selector] Trevor Hohns on the Australia A tour three or four months ago. He said we're going to pick you in the one-dayers and T20s but we want you to keep pushing for Test selection, don't think that part of the game is gone for you, which is always nice to hear from a selector.

"If I could get a bat in Shield cricket it would help. I haven't had a hit this year in two games, so if I can get a hit and put runs on the board and keep keeping well, I'm sure opportunities will come my way."

Peter Siddle will captain Victoria in the Shield game, having again missed selection in the XI for the second Test against New Zealand, which started on Friday. Siddle was released from the squad in Perth to return to Melbourne to play in the Shield game.
