CAN'T WIN IT, CAN'T USE IT The numbers behind West Coast's form slump
The four-time All-Australian defender injured his right ankle playing in a scratch match last week when serving an AFL suspension for striking.
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.
