Ross Lyon didn't out and out deny, because that would only lead to more questions.
What he did say was "I haven’t had one conversation with Aaron about that (retirement)."
“He’s really keen to get back, I think the timeframe is late in the season, about round 17."
RL also said the reports of Sandi's proposed retirement were unsubstantiated and unattributed.
Most likely, this was just a rumour, created by one of the too many third-rate journos around, looking for a no-effort story to be published, by asking a loaded question, drawing an instant conclusion, then getting a second bite of the cherry with a stock standard follow-up 'Freo denies rumour' story.
