Lyon was not listed in NSW's 12-man squad for Saturday's match against undefeated Western Australia at Sydney's Cricket Central, after making his return for the Blues a fortnight ago.
AAP has been told there is no injury concern and Lyon is expected to play in the Sheffield Shield match against Western Australia at the SCG starting Monday.
Lyon played his first domestic game back for the Blues last month in a 50-over fixture against South Australia, before facing Victoria in the Sheffield Shield last week.
He took one wicket across both games, but got through his 45 overs unscathed.
Another missing from the match will be former captain Kurtis Patterson, who has been dropped one week after being left out of the struggling Blues Sheffield Shield side.
In-form allrounder Jack Edwards is also out with the Blues managing both his workload and some minor niggles.
NSW's struggles in red-ball cricket have not extended into the one-day format with the Blues having won two of their opening 50-over matches this season.
NSW: Ollie Davies, Ben Dwarshuis, Matthew Gilkes, Chris Green, Moises Henriques (capt), Daniel Hughes, Hayden Kerr, Blake Macdonald, Jack Nisbet, Jason Sangha, William Salzmann, Sam Konstas.Â
