The Ballarat Football League has launched an investigation into a tackle by Bacchus Marsh ruckman Daniel Burton.
Darley's Andrew Azzopardi was taken to hospital with concussion after being tackled by Burton at Maddingley Park on Saturday.
BFL operations manager Shane Anwyl confirmed the incident had been referred to the BFL's investigations officer after an approach by Darley about the tackle.
He said the investigation had officially begun on Thursday.
Burton was not reported by umpires on the day or match review panel.
Under AFL Goldfield guidelines, the investigations officer has 10 days to carry out the investigation process.
An extension of up to 10 days may be granted by BFL if additional time is required.
Burton is the reigning BFL best and fairest. He also won The Courier player of the year award last season.
He will line up against Melton South at Melton Recreation Reserve on Saturday.
Other BFL round eight games: Ballarat v Sebastopol, Lake Wendouree v Melton, East Point v Sunbury, Redan v North Ballarat City.
SUNBURY will again turn back the clock in a bid to notch up its second consecutive win on a Ballarat ground.
The Lions' senior players will travel together by coach to the Eastern Oval to take on East Point.
Senior coach Travis Hodgson adopted what was once regular travelling arrangements for the trip to Lake Wendouree last round, in the hope a different routine would have the players better prepared.
The Lions' win over Lakers was their first win in Ballarat in two seasons.
BALLARAT's Lachy Dawson is not getting the same time off that his Swans' teammates are getting this year.
For the second time this year the Footscray VFL-listed Dawson returns to Alfredton after a game with his former club Hamilton in the Hampoden league.
He has taken on the extra duties when Ballarat has had breaks to meet the demands of Footscray, which is keen to see him playing as much as possible.
He was among Hamilton's best players.
