A Victorian man accused of killing another spectator in a fight after a game of country football has been granted bail but is banned from western Victoria.

Steven Saunders, from Portland, was charged with manslaughter after handing himself in to police on Thursday over the death of Darren Bell at Heywood in the state's southwest on Saturday.

Saunders, 45, appeared before the Melbourne Magistrates Court later with a black eye.

The court heard Saunders allegedly punched Mr Bell, 45, after a South West District Football League game between Heywood and Portland club Westerns at Heywood Recreation Reserve.

Mr Bell fell, hit his head on concrete and was knocked unconscious, prosecutor Tim Bourbon told the court.

He suffered a cardiac arrest and could not be revived by paramedics.

Mr Bourbon said Saunders contacted police on Tuesday to tell them where he was, and negotiated to hand himself in on Thursday.

Also on Tuesday former Essendon AFL player Nathan Lovett-Murray, who started his playing career with Heywood, posted a $5000 reward for anyone who could locate Saunders.

In court on Thursday, Saunders' defence barrister Philip Skehan said both Saunders and Mr Bell had been drinking from midday on Saturday until the altercation at around 5.30pm.

"The deceased has his part to play," he told the court.

The two men are believed to be cousins and both have strong ties with Heywood Football Club, where Mr Bell's brother Michael is president and Saunders' brother Jason Saunders is coach.

Magistrate Gregory Robinson granted bail, which was not opposed by police.

Saunders will have to live in NSW and has been banned from entering any part of western Victoria or southeast South Australia.

He is expected to return to court in September.
