It was initially suggested the premiership-winning pivot would return in time for Friday's Pirtek Stadium clash.
However that is not expected be the case.
A round 11 return against the Storm at Pirtek Stadium on Monday, May 23, is the more probable scenario.
"We are just giving him some space at the moment," Eels club captain Tim Mannah said on Sunday.
If the Eels can get under the cap by the time they meet Souths, they will need to win 12 of their last 15 matches to qualify for the NRL's final series.
It was a feat they achieved in 2009 in their surge to the grand final.
"We can't get caught up in that big picture and get too worried about winning 12 from 15," Mannah said. "If we do that we will lose focus on the job at hand."
