The Saints' on-field leadership structure remains unresolved despite strong speculation the club is likely to appoint a single captain for 2008 from one of last season's co-captains Nick Riewoldt and Lenny Hayes.

St Kilda chief executive Archie Fraser said the club's leadership group is still working through the issues just a week out form the start of the new season.

"They wanted to get the NAB Cup final out of the way and I'm sure over the next couple of days they'll come up with a final decision between Ross (Lyon) and the footy department and the match committee," Fraser said.

"Right now, as it stands, Nick and Lenny are the two captains."

Riewoldt was reluctant to add to Fraser's comments, made on Tuesday morning at the announcement of a $3.45 million State Government funding package for the Saints' new training complex at Frankston.

"I'm not sure what the hierarchy of the club is thinking," Riewoldt said.

"Lenny is a terrific leader and he's proven that he can do that role as well before and … the co-captaincy has worked well before."

"Whichever way the club want to go, I will support and get behind 100 percent."

Meanwhile Riewoldt said his knee was coming good after a bout of tendonitis interrupted his pre-season.

"It was just precautionary in the pre-season to miss those first few games but it's pulled up really well the last two weeks and another two weeks off now will do the world of good," Riewoldt said.

Asked when he expected his knee to return to full strength, Riewoldt said, "It's hard to put a figure on that sort of stuff but I'm capable of playing and I think I'm contributing well to the team and the knee's not going to stop me from doing that."
