The Manly Warringah Sea Eagles have been dealt a blow ahead of their Round 13 clash against the Newcastle Knights, with scans confirming that Jake Trbojevic has suffered a torn calf injury.
The star forward is expected to be out for up to six weeks, leaving a significant gap in the Sea Eagles' pack.
Adding to their woes, Ben Trbojevic is also set to be sidelined for an extended period due to a hamstring tear sustained in the win over the Canberra Raiders.
