Veteran Will Schofield will replace McGovern and keep his spot from last week's loss to Brisbane.

The Power will go in as named on Thursday with Kane Farrell the only inclusion for Xavier Duursma (hamstring).

The Eagles made three other changes from last week with Tom Cole, Tom Hickey and club debutant Jamaine Jones replacing omitted trio Oscar Allen, Josh Rotham and Jack Petruccelle.
