Lupe Ole Soaga qualified for the region's premier football club tournament, being held in Vanuatu, from a qualifying event held in Apia, Samoa in February.
But up to 12 players from that series will miss the finals due to registration rules.
Team manager Lai Tautiaga explained why.
"There are quite a few issues which surfaced this year. And it's our first time to be informed of such regulations. But we have players who we thought that the qualifying round was sufficient for them to attend the finals; however, it was a different story.
