Luton Town have signed defender Dan Potts on a two-year deal following his release by West Ham.
Potts, who can play left-back or centre-half, made 13 appearances for the Hammers after coming through the east London club's academy.
The 21-year-old has also had loan spells with Colchester and Portsmouth.
"He's a good talker and a good organiser, so although he's only 21 he's got experience," Luton manager John Still told his club's website.
"He's always been a player that we were interested in if it became possible."
