The Sun says Morris will be told he has one last chance to stay on the straight-and-narrow at Elland Road after a series of off-the-field incidents.
Morris is now available for selection at Portsmouth next weekend after missing four games while Leeds conducted an internal inquiry into his alleged breach of contract.
"Disciplinary proceedings against Jody Morris were concluded this morning in accordance with the procedures set out in his contract of employment," a club statement said. "It should be noted that these proceedings did not relate to matters forming the subject of the on-going police investigation."
The Yorkshire Evening Post states that Morris has been working with a personal trainer during his time away from the club and is expected to slot straight back into training.
Morris' return is seen as a major boost as United look to start their bid for Premiership survival at Fratton Park, after a miserable run of results against the top teams.
