Integrating Selenium scripts written - using TestNG with Slik Central test management tool

I've developed automation scripts using Selenium and TestNG. Can we integrate developed automation scripts with manual test cases documented in silk central? My Client wants to kick-start the execution of automation scripts from Silk Central itself.

I've made some groundwork and got to know that Silk central supports Junit. Please let me know how to run the scripts developed using TestNG in silk central.

Thank You
