Narrative:
Nashville approach slowed us to 170 KTS and vectored us on to 23 mi final for runway 20L. We called airport in sight and were cleared for a visual approach. We then saw an (medium large transport) high to our left (500-800 ft above us and descending) turning onto the localizer. At the same time, approach called and cancelled our approach clearance and gave us a left turn to 130 degree (70 degree left turn).) almost immediately TCASII alert sounded for traffic ahead of us. We were then asked if we had the (medium large transport) in sight. We said yes and were cleared for a visual at 'min approach speed.'

Title: VISUAL SIGHTING AND TCASII CAUSED ACR FLC TO TAKE EVASIVE ACTION DURING SEQUENCING FOR VISUAL APCH.
Narrative: NASHVILLE APCH SLOWED US TO 170 KTS AND VECTORED US ON TO 23 MI FINAL FOR RWY 20L. WE CALLED ARPT IN SIGHT AND WERE CLRED FOR A VISUAL APCH. WE THEN SAW AN (MLG) HIGH TO OUR L (500-800 FT ABOVE US AND DSNDING) TURNING ONTO THE LOC. AT THE SAME TIME, APCH CALLED AND CANCELLED OUR APCH CLRNC AND GAVE US A L TURN TO 130 DEG (70 DEG L TURN).) ALMOST IMMEDIATELY TCASII ALERT SOUNDED FOR TFC AHEAD OF US. WE WERE THEN ASKED IF WE HAD THE (MLG) IN SIGHT. WE SAID YES AND WERE CLRED FOR A VISUAL AT 'MIN APCH SPD.'
