Defensive coordinator Legi Suiaunoa and receivers coach Kefense Hynson are poised to leave the University of Hawaii football program and join the Oregon State staff.

An official announcement could be made as early as today.

Suiaunoa is expected to coach the defensive linemen. Hynson will coach the receivers. Jonathan Smith was hired as OSU’s head coach last month, replacing Gary Andersen, who resigned on Oct. 8.

Suiaunoa and Hynson were members of UH head coach Nick Rolovich’s initial staff. Rolovich was hired as Norm Chow’s successor in November 2015.

Suiaunoa, who coached the Rainbow Warriors’ defensive line in 2016, was promoted to defensive coordinator in February after Kevin Lempa resigned to accept a position at Michigan. This season, the Warriors were hindered because of injuries and eligibility issues. They are ranked 106th among 129 FBS teams in points allowed (33.9 per game) and 114th in total defense (458.8 yards per game).

Hynson was instrumental in the development of slotback John Ursua, who was among the nation’s leaders in receiving before suffering a season-ending knee injury.

Suiaunoa and Hynson are considered influential recruiters.

The Warriors will have to fill four positions on the coaching staff. Chris Naeole resigned as offensive line coach in October. The NCAA also approved a 10th full-time assistant coach’s position beginning in January.

The Warriors will be seeking their seventh defensive coordinator since 2013. Previous coordinators were Thom Kaumeyer (2012-2013), Kevin Klune (2014), Tom Mason (12 games in 2015), Abraham Elimimian (one game in 2015), Lempa (2015) and Suiaunoa.
