Port Adelaide have dropped high-profile recruit Jack Watts for their AFL clash with the Western Bulldogs.
The former No.1 draft pick has not done enough to warrant selection, Power coach Ken Hinkley says.
"Jack knows his form has not been at the level he would like it to be. He understands the reasons," Hinkley told reporters on Wednesday.
The other players to miss out on Thursday night's game are small forward Jake Neade and in-form defender Tom Jonas, who has been ruled out with a hamstring injury.
The Power have recalled veteran Lindsay Thomas, defender Jack Hombsch and young forward Todd Marshall.
"Their form has been really strong so obviously there comes a point where you like to reward great form," Hinkley said.
He said Watts was still part of Port's plans but he needed to go back to SANFL level and perform.
"If you play well, you find a way back in. It is not different to any player - that is what Lindsay Thomas has done."
