The Warriors coach has made three changes to his starting side for this Friday's NRL match against the Titans, with Keighran being dropped to the bench in favour of debutant Chanel Harris-Tavita.
Kearney says regardless of Keighran's exclusion, he's not to blame.
Karl Lawton's been named at hooker in place of the injured Issac Luke.
Leeson Ah Mau will start in the front row with Bunty Afoa moving to the bench.
