In his VFL debut, 18-year-old Viney was crunched by Geelong veteran David Wojcinski after receiving a handball from teammate Tom Couch in the last quarter of Saturday's curtain-raiser between Geelong and the Casey Scorpions at Simonds Stadium.
Wojcinski was not reported at the time.
Demons' football manager Josh Mahoney said the club had not lobbied for the incident to be investigated and would not appeal any VFL decision not to penalise Wojcinski.
The VFL is expected to announce its finding around noon on Monday.
"The VFL has had a lot of coverage of it so I think the commentary around the incident, the fact it was in-play and they’ve got vision of it, I don’t think we have to take it any further," Mahoney told SEN radio on Monday morning.
Freakishly, Viney was one of three Scorpions to suffer broken jaws during the clash with the Cats. The others were fellow Melbourne-listed youngster Jordan Gysberts and Scorpions utility Wade Lees.
Gysberts underwent surgery immediately after the game in Geelong on Saturday night, while Viney received an operation on Sunday. Both are still recovering in hospital and are expected to be sidelined for six to eight weeks.
Mahoney said Viney - who had gathered 18 possessions (including 10 contested) before being injured - was an exciting talent.
"He went into that game and straight away was involved in it," he said.
"His work around the stoppages and inside is very good, and his attack on the ball is very good, so if he continues to develop he's going to be a very good player."
Melbourne coach Mark Neeld would not comment on the incident, but said everyone at the club was upset that two young players had such serious injuries.
"Disappointing, disappointing," Neeld said. "Two broken cheekbones in the VFL ... don't want anyone to have to go through that. They are both in pain."
Neeld said the club's thoughts were with the players and their families who were distressed.
"It's footy though. It is a contact game," Neeld said.
