South Sydney has confirmed that Greg Inglis will definitely not start in Monday night's crucial round 12 clash against the Panthers.

However, he remains on track to make his return from injury in next Sunday's much-anticipated match against his former Storm teammates.

Speculation has been rife that the star centre would make a return for the Monday night game at Penrith's Centrebet Stadium, despite not being named, but the club has confirmed that won't be happening.

"He definitely won't be playing tonight," South Sydney media manager Jeremy Monahan told NRL.com on Monday morning. "I spoke with the coach last night and he said he's out. Everything is on target for him to return next weekend though."

Inglis, who resumed training at Redfern last week, will be keen to play on against the Storm on Sunday at ANZ Stadium to get a game under his belt ahead of the naming of the Queensland team next Tuesday for Origin II on June 15 at ANZ Stadium.

Since Inglis plays left centre, he will be a welcome addition to the Maroons for Meninga, who lost centre Willie Tonga after his Wednesday night heroics when he played 60 minutes of game one of the 2011 Harvey Norman State of Origin Series with a partly dislocated shoulder.

Inglis was overlooked for the Origin opener after hurting his hip in the Anzac Test match against New Zealand three weeks ago.

The 24-year-old carried out the Origin shield, alongside Maroons legend Billy Moore, before kick-off at Suncorp Stadium.

Monday night's game is crucial for both South Sydney and Penrith. A loss will see the Panthers join four other teams - the Raiders, Sharks, Titans and Eels - at the wrong end of the Telstra Premiership table with a 3-8 win-loss record in the battle to avoid the wooden spoon.

A win for the Rabbitohs would put them in equal eighth place (5-6) with the Tigers and Knights.
