Wade Graham admits he's unsure if he'll be fit for next month's State of Origin series opener after suffering a frustrating recurrence of his hamstring injury.
Graham lasted just 27 minutes of what was supposed to be his return game in the Sharks' nail-biting 22-20 win over Parramatta on Saturday.
The NSW back-rower spent the better part of the game on the sideline with an ice pack on his left hamstring after it gave way in the first-half.
It gives him just three weeks to prove his fitness before NSW coach Brad Fittler reads out his side for the June 6 series opener in Melbourne.
The Blues are well-stocked for back-up options with the likes of Tariq Sims and Jack de Belin pushing their cases for a representative call up.
And while Graham desperately wants to represent his state again, the difficult nature of hamstring injuries is clouding his chances.
"I just have to get through a game for Cronulla first," Graham said when asked if he'll be fit for Origin I.
"Origin's probably not even on the radar for me at the moment now.
"If I can't get through 80 here, that's got to be the first focus.
"There's still a bit of time but I'm more focused on here."
The timeframe for Graham's return is unclear and while the injury-hit Sharks want him back on the park sooner rather than later, they'll take no risks.
Skipper Paul Gallen is a chance to take on Canberra next Sunday however fellow veteran forward Luke Lewis will be out for several more weeks with a calf strain.
Jayson Bukuya will also return after this week being hospitalised with a virus, though Scott Sorensen suffered a suspected broken hand.
Graham said he would be cautious with his rehabilitation.
"I did a pull of the hammy that I did originally so it's not ideal, it's pretty frustrating," Graham said.
"I trained well throughout the week, it felt good to start the game, felt good in the contact, felt good running and kicking.
"It's one of those things, it's rugby league sometimes."
