Flight Crew Returned To Clearance
Environment - Non Weather Related; Procedure
We were on the RYYMN 2 RNAV Arrival into BNA. As we were crossing JNKNS waypoint we encountered wake turbulence from the preceding aircraft. The aircraft rolled and the autopilot disconnected as we were starting our turn at JNKNS. Because of the wake turbulence and autopilot disengagement we did not turn immediately crossing JNKNS but we did very shortly thereafter. ATC never questioned or queried us about our track and the remainder of flight was normal and uneventful.As long as there are aircraft flying on the same arrival; there is always the risk of a wake turbulence encounter. It is and will always be important for the crew to be aware of the potential risk of such an encounter no matter how small.
B737-700 Captain reported encountering wake turbulence on arrival into BNA.
