Armstrong went on to have stints with the 49ers and Giants before signing on with the Browns in 2018. Cleveland brought him back on a one-year deal last offseason but cut him coming out of the preseason.
He signed on with the Saints shortly afterward in September of last year but was cut after a month. The Cowboys signed him in December and became an unrestricted free agent this offseason.
In 2019, Armstrong appeared in six games but did not record any statistics.
