Nathan Brown wants to move on from his beef with Wayne Bennett after apologising for a spiteful retaliation against his fellow NRL coach.

Brown has expressed regret for including his Brisbane counterpart's family in a sledge after Newcastle's 15-10 NRL win over the Broncos on Saturday night.

Some argued Brown's comments had been misinterpreted and instead referred to Bennett's "football brain" but the coach appeared to confirm it was personal.

"We all become quite resilient. We cop our fair share over our journey but we dust off the next day and get on with it," Brown told the Nine Network.
