Following his appearance on Star Trek in 1967, Burns appeared in an episode of the short lived ABC series The Invaders, with fellow (and future) Trek alumni Byron Morrow, Hal Baylor, and Ed Long; along with stuntmen Troy Melton and Glenn R. Wilder.
Two years later, Burns returned to television for a role in an episode of CBS series The Wild Wild West, titled "The Night of the Cossacks", written by Star Trek writer Oliver Crawford. The episode also featured the stunt work of future Trek stuntman Eddy Donno.
Burns final noted television appearance was in a 1969 episode of another short lived ABC series, The New People. The episode did not feature any noted Trek alum.
