The Bombers coach was bemused by the decision in which his defender Henry Slattery was penalised for walking the ball across the goal line.
The AFL this week admitted umpire error gifted Hawk forward Lance Franklin a goal from the decision.
Knights said he would speak to AFL umpires’ boss Jeff Gieschen and, having done that, he was satisfied the matter had been put to bed.
“I think it may be a touch clearer now that it’s been seen in the light of day,” Knights said on Tuesday morning.
“Also, Jeff Gieschen’s come out and said ‘this is the way the rule will be applied and the way it will be adjudicated’, so it’s a bit clearer.”
Knights admitted his team had been struggling to come to grips with the rule and had only last month been drilled on it, believing it had caused his team to concede goals during the season’s early rounds.
“Only two weeks ago we went through the rule and walked through it with our whole playing group,” he said.
“I guess that’s why probably Henry and Cale [Hooker] were so animated at the time because we had spoken about it at length and because it was actually causing us some issues.
“We were actually keeping the ball in play from nearly impossible positions - nearly over the line - so we had to clear it up because it was actually costing us goals.”
The Bombers led by 23 points when Slattery gave away the free kick on Saturday night and when Franklin added another goal 30 seconds later, the margin was cut to just 11 points.
Knights admitted needing time to compose himself - and his player - at the three-quarter time break but said he didn’t direct any of his angst in the direction of the whistle-blowers.
“There was a sense of frustration, I’ll be upfront about that,” he said.
“You know sometimes you just have to, I suppose just clear your mind a little bit and just get back on track.
“I thought Henry was a bit stiff and I spoke to him about that when I first got out to the huddle and just tried to calm him down.
“The umpires have an amazingly tough job and I have a lot of respect for what they do … I’ve got no issues with the umpires at all.
“It’s just one of those calls that was made and it’s been handled well and we move on.”
