Brisbane Roar coach John Aloisi today confirmed goalkeeper Michael Theo is injured and will not travel for his side's clash against Wellington Phoenix on Saturday.
The five-time Championship-winning keeper has a quad strain sustained in last weekend's 2-1 win over Central Coast Mariners.
Theo trained earlier in the week but has not finished two sessions since and will sit out this weekend's game in the hope of being fit for next week's clash with Adelaide United.
Jamie Young, who played 24 games for the Roar last season when Theo was out through injury, will don the gloves again for the Roar against Phoenix.
"Jamie will just slot in and I am sure he will do a great job," Roar boss John Aloisi said.
"He's been training really well. Even when he didn't start in the first two game he's didn't put his head down.
"He just kept going and that shows the rest of the players to keep working hard because you don't know when the opportunities comes up and he (Young) gets that this weekend."
Young played a starring role in the Roar's 1-0 Westfield FFA Cup loss to Western Sydney Wanderers in August and the 30-year-old admitted he's relishing the opportunity to tackle the Phoenix.
"The analogy is a week is a long time in football and this is certainly evidence of that. That's how it has gone in this case and I will prepare as I normally do," Young said.
"It is important to work hard if you are playing or not playing and it is important to try and improve facets of my game and I try to do that on a day-to-day basis."
With Theo out, 18-year-old Andre Jannese comes into the Roar squad for Saturday's game.
