The Magpies will meet with the AFL on Wednesday to discuss a range of issues arising from the first four rounds, including Collingwood publicly pointing out their displeasure after umpire Scott McLaren made contact with Shane O’Bree.
Knights said there had been no breakdown in the Bombers' relationship with the umpires, and was pleased with the feedback the club had received from the league's men in white.
"We had an umpire out last week and he did some work with our players and with David Hille and Patrick Ryder," he said on Tuesday.
"We found that beneficial, so I don't think from our perspective there's deterioration in the relationship between players and umpires."
Knights said the Bombers had been focusing on ensuring their players avoided contact with umpires, after Collingwood's Heath Shaw, the Brisbane Lions' Simon Black and Port Adelaide's Matt Thomas were all referred to the tribunal over the past fortnight for such a charge.
"In regards to the accidental contact between umpires and players at times, we're educating our players to try and avoid that umpire contact, but occasionally arms and legs get tangled up and sometimes it's unavoidable," he said.
"We've just got to make sure we educate our players to make sure they're doing their best to make sure they're staying out of the umpires' way and to focus on the ball."
Knights said it was "fraught with danger" to comment on the McLaren-O'Bree incident that had dominated news on Monday following Collingwood's round four win over the Brisbane Lions.
He did say he has no concerns about how the umpires will approach Saturday's Anzac Day match after they meet with the Magpies on Wednesday.
"I've got no issues for Anzac Day," he said.
"The three umpires will be under the focus of the football world and they'll call it on its merit, and that's all we expect."
