Narrative:

Flight on approach to den runway 8R. We were on 5 mi final 2 dots high on GS having just been cleared to follow 2 jets to the runway for a visual approach and told to switch to tower frequency. Immediately after check in with tower a white cessna 172 or 182 triggered our TCASII warning at 300-500 ft below us. The cessna then appeared coming out from below our aircraft on the right side. We were on heading 080 degrees and the cessna was heading 180 degrees. Tower told us after we reported the near mid-air that the cessna was under approach control direction and jurisdiction. I talked to approach control by phone and they filed a preliminary near mid-air report.
