Olly Lee has extended his stay at Dagenham & Redbridge until 7 May.
The 19-year-old has played four games since joining the League One outfit at the start of the month in their fight to avoid relegation. The Daggers are a point above the relegation zone and have a crucial home match to come against Plymouth Argyle on Good Friday.
Lee said: "I am desperate to keep Dagenham & Redbridge up, to be honest. I have really enjoyed being part of everything at the club. The lads have been great and it's a great experience for me to be fighting to save a club from relegation at this stage of my career.
"If I could help to keep the club in League One and get eight to ten games under my belt during my time here, then that would really help me to push on for next season."
