Carlton coach Michael Voss says the Blues’ superstar Sam Walsh will spend his fourth consecutive week on the sidelines after being ruled unfit for this week’s Good Friday match against North Melbourne.

Walsh’s much anticipated return will have to wait for one more week, when Carlton take on the Crows in a 6 day turnaround for next week’s Gather round in Adelaide.

He underwent a running session on Wednesday at Ikon Park with high performance staff.

Voss is hopeful the 22 year old co-vice captain’s recovery will soon be complete.

“We’ve been pretty steadfast in our position with him,” he said.

“We’ve taken a pretty steady approach and he’s had some milestones that he’s had to achieve and we’ve stuck to those milestones.”

One of those last milestones was being able to train again fully yesterday which, Voss said, he was able to do.

“Barring him not pulling up well from that particular session – which I’m led to believe he’s OK – then he’ll play next week,” he said.

With the absence of Walsh on Friday afternoon, Carlton will also be without Jack Martin and Matt Kennedy who are both out with calf injuries.

“Another person needs to step up and get the job done – it’s been a real signature part of our team, when one man goes down the next man comes in,” he said.

“We’ve been a pretty settled side, but unfortunately Matty hasn’t come up.”

Tomorrow’s game will be the first time the Blues play on Good Friday, and Voss is confident in his team’s ability to get the four points while joining North to raise money for the Royal Children’s Hospital.

“We’ve got a role to play, so we are really grateful we get that opportunity,” he said.
