Upper Hutt and Petone are both battling to field teams in the Wellington premier rugby league competition this season.
The clubs have advised Wellington Rugby League of their lack of playing numbers and a decision on their futures will be made on Friday.
The eight-team competition kicks off on Saturday week (April 5) but Wellington Rugby League general manager Jason Hemson gave the impression it could be a seven-, or even six-, team premier grade.
Hemson said that Upper Hutt, which celebrated their 50th anniversary in 2011, were the biggest concern.
He said it seemed much of last year's squad members had either retired or changed clubs.
"We've checked with Upper Hutt rugby and they haven't gone there," Hemson said.
He said one option was for Upper Hutt and Petone to combine their premier and reserve squads to make one squad and then promote the Titahi Bay Marlins and Trentham Titans from senior first to premier reserve.
