Mitchell Banner Biography

David Rodan and Jacob Surjan among seven delistings announced by Port on Friday.

The seven delistees also include Simon Phillips, Mitch Banner and rookies Daniel Webb, Mitch Curnow and Jarrad Irons.

"David embraced his new opportunity from the outset and is a player who won't be forgotten by Port Adelaide supporters who admire his flair as a midfielder and willingness to take on opponents and attack the game," Power football operations manager Peter Rohde said.

"He's popular within the club as well and is respected for his work ethic, ability to overcome serious injuries, his personality and what he does off the field to promote football in our multicultural community."

MCG security confiscated a banner protesting Lance Franklin's association with a controversial clothing line during the Hawks' match against Brisbane.

A member of lobby group Collective Shout unveiled a sign reading "Give porn tees the boot Buddy."

"If you want to support your team, and bring along material to do that, that's fine, that's what a football match should be, but it's not for any other use beyond that," AFL spokesman Patrick Keane said.

Mitch Banner has worked hard on his defensive game in an effort to consolidate a place in the senior Power side.

"In under-18s it's all about attack. You just want to get a kick to hopefully get yourself drafted by an AFL club," Banner said.

"Now, it's about tackling, getting back to help out the defenders and putting pressure on the opposition to help the team. That's pretty much what I model my game on now. I figure if I'm doing the defensive stuff and helping the team out the offensive stuff will come."

Mitchell Banner makes his AFL debut for Port Adelaide at Football Park with 18 disposals (11 kicks and 7 handballs), 2 marks, 4 tackles and a goal in a 14-point win over North Melbourne.
