PORT Adelaide will confirm two changes — including the dropping of two-game ruckman Dougal Howard — later today when AFL teams for the Power-Brisbane Mother’s Day clash are lodged.

The Power will recall key defender Jackson Trengove from suspension and regain All-Australian forward Chad Wingard from concussion.

They will replace Howard and midfielder-forward Sam Gray.

Wingard trained Friday and coach Ken Hinkley will rely on medical advice in the next 36 hours before confirming the goalsneak as a certainty against the Lions at the Adelaide Oval.

“We will be really careful — no risk,” said Hinkley at Alberton on Friday.

Hinkley praised Howard’s enthusiasm but noted the 20-year-old would be managed, as would the Power’s makeshift ruck stocks.

“I love what Dougal brings as a young player — and I know he wants to do it every week,” Hinkley said.

Trengove and forwards Charlie Dixon and Justin Westhoff will share the ruck duties on Sunday.
