Crows mourn Phil Walsh: 'just got to get through today'

ADELAIDE Crows coach Phil Walsh has been described as a 'leader of men' by his club.

Crows chairman Rob Chapman and CEO Andrew Fagan spoke to the media this afternoon, describing the character of the much loved coach, who was found stabbed to death in his Adelaide home this morning. 

Mr Chapman said the club was in an "unprecedented crisis".

"There's no rule book," he said. 

"He's a coach, he's a leader of men. Unambiguous, straight up and down, clear messaging, inspiring, genuinely cared.

"It's probably why he had the longevity in our system in the football community that he's had 30 years. Not a lot of people do that unless you genuinely care and you're good at your craft."

The Adelaide Crows Sunday game against Geelong has been cancelled, but the remaining seven games will go ahead.

Mr Fagan said that at some stage, the club will have to confront the logistics of playing football again.

"One decision we made really quickly is that David Noble just takes control of football. He's our general manager of football operations. That may seem logical, but just take control, take control of messaging, communication.

"We had a State League game tomorrow at Port Noarlunga, that won't go ahead.

"You're going to have to have the lens on next week quickly, so we'll have to give that further thought today and tomorrow."

He said the community support has been extraordinary, but the club are still in deep shock.

"It's one of shock and disbelief and the people walking through the corridors are looking at each other shaking their head," he said.

"It's difficult to contemplate regardless of tragedy we've faced individually in our lives, it's a big one and hard to comprehend, but we've got to.

"I can't speak for tomorrow, we've just got to get through today."

"Todayis all about wrapping our arms around the Adelaide Football Club community." - Rob Chapman #weflyasone

EARLIER: THE 55-year-old head coach of the Adelaide Crows, Phil Walsh, was stabbed to death early this morning, and police say his son  has now been charged with murder.

Police and ambulance officers were called to Walsh's family home in Somerton Park, Adelaide in the early hours of the morning after reports of a domestic dispute.

While paramedics tried to treat Walsh at the scene, he died at home from multiple stab wounds, police have told reporters in South Australia.

Police later searched for and found Walsh's 26-year-old son, who was now undergoing a psychological assessment at Flinders Medical Centre.

Walsh's wife was also taken to hospital for treatment of a stab wound to her leg.

Senior police said the stabbing death was a tragic family situation.

"It is not just that he is a high profile person. It's absolute terrible when a family is torn apart.''

"For any family, regardless of who it is, is one of the worst things that you could imagine that could happen to you," he said.

"The only thing that is different with this is that he has a high profile. The pain and suffering of the family is no different."

Shocked Adelaide players were arriving at Adelaide Oval.

"The Adelaide Football Club is devastated at the sudden passing of Senior Coach Phil Walsh in the early hours of this morning,'' a statement released by the club said on Friday morning.

"We ask if you could please respect the privacy of his family, as well as our players, coaches and staff, at this extremely difficult time. The club will hold a media conference at some stage this afternoon."

There had been an argument between the son and Mr Walsh, police confirmed.

They would not divulge what the argument was about.

The son normally lives at the Walsh family home. A knife was found at the scene.

The son was found at another location in First Avenue at Glenelg East.

SA Police Superintendent Des Bray said police were called to the home shortly after 2am.

"I can't tell you anything about the argument or the circumstances of that, but as a result of that both Mr Walsh and his wife received the wounds and the wounds ultimately caused Mr Walsh's death," he told reporters.

"As you would appreciate, the investigation is in its infancy," he said.

"We can't speak to the son at this stage and obviously [the] wife is receiving treatment so as the investigation unfolds, I'm sure we'll find out exactly what happened."

The son was detained for psychiatric assessment and was under guard at hospital.

The well-known coach played more than 120 VFL games for Collingwood, Richmond and the Brisbane Bears, before moving into coaching at Geelong, Port Adelaide, the West Coast Eagles and lately, the Crows.

Police said the investigation into Walsh's death was "still in its infancy", and the Crows club is expected to make a statement later today.

Phil Walsh remembered as passionate coach

Phil Walsh (15 March 1960 - 3 July 2015) played for Collingwood, Richmond and the Brisbane Bears in the Victorian Football League (VFL) during the 1980s.

He then held the assistant coaching roles at Geelong, West Coast, and Port Adelaide.

Walsh played mostly as a wingman and made his VFL debut in the 1983 season with Collingwood.

The following year he crossed to Richmond where he spent three seasons with the club playing in 40 games. He finished his career at Brisbane and won their inaugural Best and Fairest award in 1987.

Coaching career

Walsh was the strength and conditioning coach at the Geelong Football Club, before moving to the Port Adelaide Football Club, as an assistant coach in 1999.

He was an assistant coach under Mark Williams in Port's 2004 premiership team, and in the same year was awarded the AFL Coaches Association Assistant Coach of the Year award.

In 2009 he moved on to West Coast as an assistant coach under John Worsfold.

In 2014, he returned to South Australia as an assistant coach, specialising in midfield strategy, at the Port Adelaide Football Club.

On 7 October 2014, Walsh was appointed the senior coach at the Adelaide Football Club for three years, after the sacking on Brenton Sanderson.

Walsh struggled with work-life balance

Football commentators say Phil Walsh was an obsessive coach who struggled with the balance between work and life.

They said he had been making efforts in recent times on his relationship with his son.
