Parramatta veteran Jeff Robson has left the door ajar to extend his second stint with the Eels until the end of next season after earlier declaring this campaign would be his last.

While stopping short of confirming a complete about-face on retirement, Robson is mulling whether to prolong his NRL career into 2017 when he will turn 35 as uncertainty continues to plague the Eels' playmaking options.

Parramatta's axed skipper Kieran Foran has sought a release from his four-year $5 million deal to manage a raft of personal issues while off-contract No.6 Corey Norman remains unsigned beyond this season.

Only last week Norman pleaded guilty in court to being caught in possession of a container of MDMA capsules at The Star in May and was fined $400.
