League manager Chris Bannerman said the match review committee had asked for video footage from both clubs after their fiery clash but he thought it was unlikely that footage of two unsavoury incidents would be forthcoming.

"We have requested video from both clubs but whether that will be forthcoming I don't know," Bannerman said.

"We don't have the constitutional power to second it from them so that puts more emphasis on the accuracy and consistency of what's reported by match officials."

Though most clubs take video of their matches for coaching purposes, Bannerman said the league may look at measures to compel clubs to provide video for consideration of the match review committee.

"It's possible. It's always been encouraged and I believe the league has looked at making it mandatory before.

"It's pretty obvious that most clubs do take video for their own purposes. We don't currently have the right to insist on access to that but ... we may need to look at ... our powers in that regard."

Bannerman saw both incidents on Saturday as did two other board members who have submitted reports on what they saw, meaning the review process would be thorough despite no video footage.

"There's been no collusion but from what I've seen; the reports are all pretty consistent," he said.
