Manager Dale Brooks said: "Dan has thoroughly enjoyed his time here but has gone back to Southend to pursue a contract there. He wants to be back around the place and try and impress.
"But I would like to thank Dan for his time here because he has been tremendous for us. Dan has signified that it is not about how tall you are but about how big your heart is. He's a great character with a tremendous attitude and has served us brilliantly."
Humphreys made 13 appearances during his time with Lowestoft Town and was quickly becoming a firm favourite with the fans.
Everyone at Lowestoft Town Football Club wishes Dan all the best with his future career.
