The Capitals have until tomorrow night to register Jackson with the league to ensure she can play the rest of the 2009-10 season.

A group of local businesses - headed by Actew chairman John Mackay - has raised $170,000 of the $220,000 needed to secure the world's best female basketballer and The Canberra Times understands the deal could be finalised this afternoon.

If Jackson agrees to join the Capitals and is fit to return to the court, just one of her five regular-season games in Canberra will be played at the 5000-seat capacity AIS Arena.

The rest of the games are scheduled to be played at Southern Cross Stadium - which can hold 1300 - in Tuggeranong.

Jackson's presence will boost the Capitals' profile and likely improve attendances for the remainder of the season.

Basketball ACT boss Mark Cartwright conceded moving home games to the institute could be a possibility should Jackson sign with Canberra.

''[We're] still awaiting the final medical report [to see when she would be fit to play], although I expect it to be in the very near future,'' Cartwright said.

''I will consider the stadium matter if and when Lauren agrees to play with the Capitals. There is plenty of work to do before this is a serious consideration.''

Jackson is recovering from stress fractures in her back and it is unknown when she will be ready to make a full return to the court.

The 28-year-old is still contracted to Russian club Spartak Moscow, but it is understood she has permission to negotiate with other teams.

The catalyst for Jackson returning to the WNBL after a 312-year absence was the brutal murder of Spartak owner Shabtai von Kalmanovich earlier this month.

Jackson's father Gary would not speculate on his daughter's future, but said Kalmanovich's death had taken its toll.

''They're the sorts of things you don't like anyone to see or be involved in and it was a shock to the system,'' Gary Jackson told The Canberra Times. ''She's had a lot of respect for him over the years ... If she can [play in the WNBL] it would be nice, but that's Lauren's decision.
