Veteran prop Jacob Lillyman has probably played his last NRL game for the Warriors after suffering injury in their 36-18 loss to South Sydney.

Lillyman left the game in Sydney on Friday with a suspected torn bicep and is set to add to a sizeable injury list at the beleaguered club heading into Sunday’s final home match against Manly. Their season ends a week later away to Wests Tigers.

The 33-year-old Queensland front rower isn’t contracted beyond this year, meaning his ninth season at the Warriors is likely to be his last.

Canterbury-bound playmaker Kieran Foran is also in doubt this week after suffering a back injury.

Assistant coach Andrew McFadden says a decision is yet to be made on the pair.

“It doesn’t look good for Jacob at the moment – suspected torn bicep,” McFadden told NZME.

“We will get scans to confirm that but it is very unlikely he will play any further part in the season.

“Kieran – not sure at the moment. It is a back injury so we will just have to wait and see how it responds.”

McFadden admitted the Warriors were at the “bare bones” of their roster and said a lack of forward depth was exposed in their second-half slump against the Rabbitohs – their seventh successive loss.
