Darlington Point Coleambally are the 10th team to commit to the West Wyalong Knockout.
It means five first round games can now be played following a big drop in teams for the usually popular pre-season event on February 22.
They join the hosts, Tullibigeal Lakes United and Griffith Black and Whites as the Group 20 teams in the competition.
Southcity, Brothers, Young and Temora represent Group Nine with Group 10 club Mudgee and Canberra Raiders Cup outfit Goulburn filling the remaining two places.
The grand finalists from last year have not returned.
The draw is set to be released on Wednesday.
Only two of the 10 teams will be knocked out on the opening night with quarter-finals, featuring the three best losers, to be played on Saturday.
