Lyon denied the club was divided and maintained the playing group were united.
"There's no issue," he said. "There might have been a few boys a little bit angry, but not everyone's going to be happy all the time in any workplace. I really don't think there's an issue. Everyone's starting to move on now."
Coach Geoff Toovey repeatedly refused to answer questions over the status of Matai and Watmough's contracts and would not be drawn on reports the club has offered the pair extensions beyond their current deals.
"I don't talk about individual contracts but those sorts of things happen at every club every month," he said. "I think Steve's been playing exceptional football and I think he'll remain playing exceptional football."
Toovey insisted the Sea Eagles camp is a happy one but admitted they were looking forward to getting away from the intense scrutiny of Sydney media. He also acknowledged the Warriors would be formidable opponents at Mt Smart Stadium, where they are unbeaten in four starts this year.
"It's good, it's really good. They're upbeat, looking forward to going over to New Zealand and probably escaping a bit so hopefully the weather will be a bit better than here but we're looking forward to it. It's always a tough game playing against the Warriors and they're playing some particularly good football and we'll need to be at our best to win.
"The Warriors are always that sleeping giant. They've got a great team, great players within the team. It's just a matter of gelling it together. They have been doing that over the last few weeks. They're a quality side and at home they're particularly hard to beat."
