The case against a man accused of fatally stabbing another man at Pasadena last August has been delayed as prosecutors wait for a peer review of a port-mortem report.

Samuel Davey, 34, died from stab wounds to his chest after an altercation involving a group of five people.

Thomas Michael Cavanagh, 31, who police allege was known to the victim has been charged with his murder.

Two drug trafficking charges against Cavanagh were dropped in the Adelaide Magistrates Court.

He was expected to enter a plea on his murder charge but prosecutors told the court that they were still awaiting some documents, including the peer-review and an analysis of phone records.

Magistrate Simon Smart agreed to adjourn the matter but told prosecutors he would allow no further delays.

Cavanagh is expected to answer the charge in March.
