Plymouth midfielder Luke Summerfield will remain at Home Park until the summer of 2008 after extending his contract with the Championship club. Summerfield has signed a one-year extension to his current deal.
The 19-year-old has broken into the first team this season and has become a regular in Ian Holloway's line-up.
The teenager has made 19 appearances this campaign and scored his first senior goal in a 1-0 win against Colchester back in August.
