Port Adelaide backman Jackson Trengove’s broken foot could prompt the AFL surprise packets to elevate rookie Kane Mitchell for a second time.

Port coach Ken Hinkley says Trengove expects to miss between eight and 10 games after having surgery on his right foot.

The key defender is likely to be placed on the long-term injury list, leaving an opening for Mitchell’s return.

The West Australian recruit played in Port’s initial three wins this season, having been elevated to the senior list when Nick Salter was injured.

Salter’s return to fitness two weeks ago meant Mitchell, who impressed in three consecutive substitute appearances, was forced back to the rookie list.

Hinkley said again recalling Mitchell to the senior squad was an option as Port prepare to play North Melbourne.

“It’s certainly something we’ll consider,” Hinkley told reporters on Wednesday.

Describing the loss of Trengove as a significant blow, Hinkley said sweeping defender Jasper Pittard would also miss at least another match with a hip injury.

Pittard was a late withdrawal from Port’s victory over West Coast which maintained their unbeaten streak.

But Hinkley said despite five consecutive wins, Port hadn’t regained respect after five barren seasons.

“I think that takes time,” he said.

“We are in a position where we need to keep turning up each week and, as I say to the players, your behaviours, they will change your outcomes.

“And the outcome for us will be that we earn more respect if we continually turn up and play like we have been able to do so far.”
