The West Coast Eagles will stand by footballer Murray Newman while he serves a one-year prison sentence for fracturing the jaw of a man who slept with his girlfriend.
Newman will remain on West Coast's AFL rookie list while serving his time for causing grievous bodily harm to Brett Marris at a Perth nightclub in November 2012.
West Coast issued a statement on Friday saying the club did not condone Murray's actions but would keep him on the rookie list for this season.
"The club believes that it will be an important part of his rehabilitation and his re-integration to society - and football - upon his release," West Coast chief executive Trevor Nisbett said.
"Since this incident occurred, Murray has been exemplary around the club, and is deeply sorry for his actions."
Newman, then aged 18, had a "deep grudge" against Mr Marris for sleeping with the AFL player's girlfriend, Judge John Staude found on Friday.
After weeks of threats from Newman on Facebook, including telling Mr Marris to "start digging a grave", the pair saw each other at the Library Nightclub in Northbridge.
Newman was sober but angry when the pair fought briefly before bouncers broke up the fight, and Judge Staude said he did not accept Newman was acting in self-defence.
"You were the aggressor, not he," he said.
Judge Staude was also critical of Newman for only showing some remorse after the verdict.
"This was not a spontaneous or instinctive reaction to a situation you did not expect, but a consequence of you developing an antipathy towards Mr Marris over a period of time," he said.
While Judge Staude accepted the sincerity of Newman's letter to his victim in which he said he did not intend to fracture Mr Marris' jaw, the judge did not accept the claim that Newman did not intend to confront Mr Marris, who was 20 at the time.
Judge Staude noted Newman's football career was important to him, citing a letter from Mr Nisbett, who said he was pleased with Newman's progress.
He also referenced a victim impact statement from Mr Marris explaining his anxiety and fear of encountering Newman again.
Judge Staude accepted the crime was at the lower end of the scale in terms of grievous bodily harm and that Newman had no prior record.
Defence lawyer David Grace pleaded for mercy and a spent conviction because a jail term could end his client's AFL career, but the prosecution argued deterrence was paramount.
Newman must spend six months behind bars before being eligible for parole.
He also has a permanent restraining order against him and cannot be within 25 metres of Mr Marris.
Newman was supported in court during the trial by West Coast teammates including captain Darren Glass, Dean Cox, Nic Naitanui and Josh Kennedy.
On his debut in 2012, Newman played four games for the Eagles, but spent last year playing in the WAFL.
