Oxford United have signed former Darlington striker John Campbell until the end of the season after a successful trial with the club.
The 26-year-old, who left the Quakers in November 2011, impressed after scoring 24 goals in 19 games for non-league Jarrow Roofing this season.
He began his career at Newcastle United and had a spell at Manchester City.
"It's a wonderful opportunity to be playing in the Football League again," Campbell told Oxford United's website.
He added: "I came down and had a look at the club and the facilities a couple of weeks ago and was very impressed by everything.
"Not just the set up but the attitude here; everything and everyone is really positive."
His boss at Jarrow Roofing, Richie McLoughlin, said he was confident Campbell could make the step up to league football.
"He's got more potential then people think," McLoughlin told BBC Radio Oxford.
"He's laid back, but with full time training and a proper physio which he needs to keep him right, I think he'll do a great job.
"I told Michael Appleton, if you get this lad fit he will get you the goals you need. He has got pace, he can read the game and most importantly he can put the ball in the back of the net. He will make the step up with ease."
