Cambridge United have handed a one-year deal to Rossi Jarvis, after the midfielder impressed during an initial one-month spell.
The 23-year-old, formerly of Norwich, Barnet and Luton, has featured in all five games for the U's this season.
"I am delighted that he has now signed for the season," U's boss Jez George told the club website.
"He has worked hard to catch up with his fitness and I believe he will add some important qualities to our squad."
Jarvis added: "I'm very pleased to have signed and I'm looking forward to being a fully fledged part of the team. Hopefully now we can push on and have a good season."
