The BFL has referred an off-the-ball incident between Darley's Jake Edwards and Redan defender Patt Britt early in the game at Darley Park to its investigation officer.

The investigation has been launched at the request of Redan.

BFL operations manager Shane Anwyl confirmed that Redan had lodged the request late on Wednesday.

The investigations officer has a maximum of 10 days to carry out his inquiry.

With Darley out of the finals after losing to Redan, the investigation will have no ongoing impact on the premiership race.

Meanwhile, Melton has confirmed youngster Ben McMahon will miss Saturday's second semi-final against East Point at the City Oval on Saturday.

McMahon was concussed early in the Bloods' elimination final win over Sunbury.

Coach Aaron Tymms hopes that with a rest he will be fit for Melton's next assignment in either the preliminary final or grand final.

McMahon was part of an extended interchange when teams were announced on Thursday night.

Another under-19 player Luke Heaney replaces McMahon for what will be his first senior game since round 10 when he broke a hand against Ballarat.

While East Point and Melton have a second chance, there will be no such comfort for Sebastopol or Redan in the knockout first semi-final at Wendouree's CE Brown Reserve on Sunday.

Redan has intriguingly named teenager Kayne Councillor in the seniors as a replacement for an injured Dean Chester (hamstring), as well as in the under-19s.
