Asked about the alleged referee contact, Hayne shrugged: "I don't know what I did.
"I tried to stay as far away as I could.
"Was it a touch or did he walk back into me? I'm not too sure.
"I really don't understand what the go is with the whole 'accidentally touching the ref thing'.
"It's probably the biggest mind blowing thing that a person can miss a week for accidentally touching a ref. It's sad for someone to miss a week for a non-aggressive thing I guess."
During his time playing with the San Francisco 49ers, Hayne was regularly sharing the field with match officials.
"They've got a pretty tricky job (in the NFL) because they stand (everywhere)," he said. "One's in the line of scrimmage, one's in the defence as well so he's got to kind of read plays and get in and out as well.
"They've been run over a couple of times as well."
While playing in the US, Hayne did have one hilarious - and public - exchange with a referee, when he was micced up for a game against the Green bay Packers.
During the game, Hayne chipped veteran official Greg Steed after receiving body contact from Packers wide receiver Jeff Janis following a 'fair catch' call.
"Aye! Are you serious?" Hayne shouted. "Hey, rules are rules, man. Rules are rules. I may be from Australia but I know them."
