Invincibile, 31, was released by fellow SPL club Kilmarnock in late January after spending eight years at Rugby Park.

The Brisbane-born attacker is now in line for his debut after being added to the St Johnstone squad for Sunday's league clash with Rangers.

Meanwhile, Jody Morris and Jamie Adams are doubts for St Johnstone.

Morris has a back problem and Adams sprained his ankle in the midweek 0-0 draw with Dundee United but manager Derek McInnes will wait to make a decision on their fitness.

Kevin Moon, who recently recovered from a serious knee injury, is also a doubt with a groin problem, but Chris Millar (hamstring) is again out and Sam Parkin (broken ankle) will not figure for the remainder of the season.

Team (from): Enckelman, Duberry, MacKay, Anderson, Morris, Taylor, Craig, Davidson, May, Samuel, MacDonald, Novikovas, Maybury, Caddis, Adams, Smith, Invincibile.
