Was UJ Puckett ever on Gunsmoke?

So I was looking at this Gunsmoke episode with a pool theme where a spectator sitting in the climax game at the end looked a lot like UJ Puckett. It was for about 5 seconds and the guy was wearing the same period clothing as the other actors but he sure looked a lot like him from the hair and facial features. Was just wondering if he made a cameo on that show or not. thank you.
