OLLIE WINES and Brent Renouf have been given the tick of approval by Port Adelaide fitness staff after both left the ground in discomfort during the Power's 60-point loss to Adelaide in the NAB Challenge on Sunday.

Renouf was substituted from the game in the third quarter after enduring a knock to his side, while Wines was keeled over in the fourth after being hit while trying to dispose of the ball.

Both should be available to play against Essendon in the Power's second and final NAB Challenge match on Tuesday 25 February, although Ken Hinkley has positioned himself to make wholesale changes to its lineup.

Injury Update: Young Power downed by Crows

"All the boys that weren't out there today will be out next week, barring injury obviously," said Hinkley.

"There are a couple out injured.

"It's one of the things about the NAB Challenge that you know you've got to play, you know the format's OK, but you worry about the injuries [you might get].

"For us to get through is really good, Renouf copped a knock, but outside of that just bruises and bumps that you expect in a game of AFL footy."
