Jones-Buchanan, 31, made his Leeds debut back in 1999 and could make his 300th Rhinos appearance against the Airlie Birds.
Coach Brian McDermott said: “Jonesy is one of those people in life who makes you glad you have met them. He is an inspirational character within our group.
“Playing-wise, he is producing some of his best rugby at the moment and that bodes well for the Rhinos and England.”
Super League champions Leeds travel to the KC Stadium without a win in three and eight points off leaders Wigan.
