Two brothers have pleaded not guilty to murdering a man in a Launceston pub.

Police allege a 28-year-old man died after he was bashed by Mitchell Clay Dowling, 42, and Jay David Blazely, 38, during a brawl at the Mowbray Hotel last month.

The brothers pleaded not guilty in the Magistrates Court in Launceston.

They were remanded in custody to appear in the Supreme Court next month.
