Three players are poised for round one after missing trials.
Winger Roger Tuivasa-Sheck, second rower Marata Niukore, and standoff Chanel Harris-Tavita won't compete in the NZ Warriors' Preseason Challenge matches.
However, they will be eligible for the opening match of the season.
Tuivasa-Sheck, dealing with a low-grade hamstring injury, will sit out today's game against Manly Warringah and the February 20 clash with the Dolphins.
His goal is to recover in time for the round one NRL showdown against the Sydney Roosters at Go Media Stadium on March 1.
Both Niukore and Harris-Tavita have slight calf injuries, but they are expected to be fit for round one.
Taine Tuaupiki, who suffered an ankle injury and missed the All Stars trial against Manly, is anticipated to be available for the upcoming trial against the Dolphins next week.
