The discovery of nerve damage has served to extend Kieran Foran's time on the injury list this season but Manly has moved to play down fears it will result in a long-term absence for their premiership-winning five-eighth.

The freshly re-signed Sea Eagles playmaker has not played since a shock round-five defeat to Parramatta and a lingering hamstring injury will also keep him out of Sunday's match against Canberra at Brookvale Oval.

Having been named to take on Canterbury, the club that had been courting him, last week, the 21-year-old was worked on by Manly medicos after some nerve damage was found in connection with the hamstring.

There was speculation the development could see him missing for several more weeks but the premiers were last night confident their medical team would have him ready to return on Friday week against Brisbane at Suncorp Stadium.

''There was a little bit of nerve damage in there so they had to do some manipulative remedial work on it,'' Manly general manager of football Steve Gigg said.

''I think they're pretty confident. It just needs time to settle down. It won't be long term.''

Foran said yesterday the injury, which also kept him out of last month's Test against Australia in Auckland, had been worse than first expected.

''I am hopeful for next week,'' Foran said.

''It's been an ongoing injury, at first we didn't think it was that bad but as we've tried to get more movement on it, it hasn't really gone to plan.

''I just want to be out on the field, and you tell yourself that it's right. But with hamstring injuries, they are a funny one.

''You can't really be out there as you may do more damage.''

While the injury is an ongoing concern there has at least been a relaxing of tension in another area thanks to his re-signing with the Sea Eagles at the weekend. Foran said staying at Manly, and deciding not to follow former coach Des Hasler to the Bulldogs, was a weight off his shoulders.

''It was a tough decision, but it was the right one,'' he said.

''I said all along it was not about money and it never came into it.

''I had the clause put into the contract because of the high regard that I hold Dessie in.

''But it was my great passion for the club and the boys that swung the decision.

''We have a pretty special bunch here.''
