Jacob Kiraz's rising campaign has suffered a sharp interruption, with the Canterbury flyer facing up to six weeks on the sidelines after suffering a calf injury during the Bulldogs' most recent outing.

The 22-year-old had surged back into form after overcoming a pre-season back injury and was building genuine momentum for a possible Origin debut.

The setback comes at a cruel time for both player and club.

Kiraz played through the injury in Friday night's game but has appeared to have suffered a moderate-grade strain.

Recovery from that level of calf damage typically ranges between four and six weeks.

Earlier, Nine broke the story, reporting the injury as โ€œsignificantโ€ and forecasting an absence of at least a month.

Kiraz had re-emerged as a serious contender for a NSW Blues jersey, with Zac Lomax under an injury cloud and Blues selectors weighing up their outside back stocks.

That possibility is now in doubt, with Game I of the series looming on May 28.

Depending on how rehab progresses, a late Origin series appearance cannot be ruled out entirely.

Before the injury, Kiraz had returned to the Bulldogs' starting side in Round 5 and wasted no time reminding everyone of his quality.

His standout showing in Magic Round included a hat-trick against the Titans, drawing praise for his backfield carries and defensive commitment.

Coach Cameron Ciraldo had noted Kiraz's effort areas as a benchmark for the squad.
