Travis Boak is set to become the first captain of Port Adelaide to wear the famous number one jumper with his surname atop it.

And his teammates will follow suit.

The AFL will trial surnames across the back of guernsey jumpers in Round 5, a weekend where Port Adelaide will wear its white away uniform against the West Coast Eagles at Patersons Stadium.

Support for the idea from the likes of AFL chief executive Andrew Demetriou and supercoach Kevin Sheedy, as well as expansion clubs Gold Coast and Greater Western Sydney, has been on public record for some time.

The names will be five centimetres in height and reduce numbers by two centimetres. 

The AFL's deputy chief executive Gillon McLachlan says the concept will bring the League into line with other high-profile codes.

"The suggestion of player names on jumpers has been a regular discussion item for the AFL in recent years," McLachlan said.

"Many fans now identify with both an athlete's name and his number with a playing jumper across most other sports, while our game has traditionally just recognised a player for his number."

It is the first substantial change to player identification on jumpers since the introduction of numbers in 1911.

The move emulates current strip designs common in other football codes such as American Football, soccer and rugby.

Port Adelaide's manager of marketing, brand and digital Stephen Shirley says the AFL's move is one supported by the club.

"The AFL is one of the few sport codes in the world to not have player names on the back of team uniforms and it does offer us some cool new opportunities in terms of branding and merchandising," said Shirley.

"Port Adelaide is fully supportive of this move and we think it will certainly help with a number of things in terms of our branding on the field and identification of players."
