Hungarian defender Timar has not started since the 3-1 home defeat by Cardiff on August 18 but is set to deputise for Benin international Reda Johnson, who is a doubt with a knee injury.
Argyle have slipped to third from bottom after six league games without a win.
Sturrock said: "Reda will be given every chance but it may be too early for him, which is disappointing.
"Krisztian obviously comes back into my thoughts. At the end of the day we have got to put a win under our belts and Krisztian should be involved in that."
