ESSENDON has all but ruled out Bomber club champion James Hird filling one of the assistant coach roles vacated on Monday.

Assistants Scott Camporeale and Ashley Prescott will both be stepping down from their positions at the end of 2010, but club CEO Ian Robson said the search for replacements is not expected to include Hird.

"We talk to James all the time because he's a tribal elder at this club and his company has had a number of dealings with us in the marketing space," Robson said on Tuesday.

"He's an incredibly busy man so I can't see him putting up his hand for an assistant role.

"Who knows somewhere down the track what he wants to do, but right now he's incredibly busy in his business life."

Robson said Camporeale's and Prescott's decisions to return home to South Australia and Western Australia respectively were made amicably with the club.

"We weren't surprised because those conversations were going on for a while now," he said.

"Their contracts were up at the end of the year as most of our assistant coaches were, so we’ve been talking about what the plans look like for 2011 and beyond.

“That triggered a range of conversations with their families and they’ve made some family decisions we respect, so we thought it was important to announce them now.

“Now we can begin to look for a fresh injection of energy and talent from some new coaches for next year.”

He said the search for replacements would start now as it was important to have the full coaching team installed before the off-season trade and draft period began.

“You really need to be clear where your infrastructure is because there are crucial decisions to be made in that period regarding list management,” he said.

“Paul Hamilton, Matthew Knights and myself have certainly had some conversations quickly about that at the start of this week.

“We’ll ... assess which candidates are available, whether they are existing coaches in the system who might be looking for a fresh start and opportunity, or players who are just coming out of the system as players.”

The Bombers will wear a special guernsey against Collingwood this Friday night for their Road Safety match, which is designed to promote the 40th anniversary of the mandatory seatbelt legislation.

Robson said the club was “delighted” the AFL showed flexibility in allowing the Bombers to don the red seatbelt sash just two weeks after they altered their jumper with a yellow armband for the Call to Arms match against St Kilda.

“When we embrace a community issue we really go at it hard. How could you not, given the very personal and compelling story David Hille has told?” he said.

“When we talked about this at the start of the year, we were very mindful we had the three big games back, to back, to back.

“Collingwood and Essendon has a special ring to it on Anzac Day and it also has a special ring to it now this year because of the anniversary of the seatbelt legislation.”

Hille is an AFL ambassador for the campaign, having been involved in a serious car accident in 1998 that killed three of his mates.

“It took some time to understand the TAC was offering me a wonderful platform to promote this message,” he said.

“In the end, I hope it’s something that’s seen as a positive message.

“I hope young individuals who don’t quite understand the ramifications of their choices to think and look after one another and their loved ones.”

VFL teams the Bendigo Bombers and the Coburg Tigers, TAC Cup teams the Bendigo Pioneers and the Oakleigh Chargers, and A-League side the Melbourne Victory will also wear seatbelt sashes on their jumpers this weekend.
