The defender has had a long road with West Ham and was clearly upset to be leaving.
West Ham revealed their retained list for next season yesterday, with some big names making their way out of the Boleyn Ground.
Carlton Cole, Jussi Jaaskelainen and Nene have also been let go with Guy Demel, Sean Maguire and Paul McCallum also heading through exit door.
Another name on the list was Daniel Potts. The defender, son for former West Ham player Steve Potts, was the Hammers Young Player of the Year in 2012 but has never made the grade at the club.
Potts has played just two Premier League games for the club and has played just once this season, in the Capital One Cup tie against Sheffield United back in August, which they lost on penalties.
He also spent time on loan at the likes of Colchester United and Portsmouth - whilst a deal to join Blackpool toward the end of this season ended after he suffered an injury.
Now he has left the club after a 12-year association he has taken to Twitter to thank the club for everything they did for him over the years.

Now Potts, who battled leukemia from the age of 12 to 16, will hope to find his feet at Luton Town, after confirming he had joined The Hatters today.
West Ham fans will no doubt wish him all the very best.
