The 29-year-old striker arrives at the Elgood's Arena with plenty of
Football League experience behind him having played for Peterborough United, Lincoln City, Boston United and Macclesfield Town who released him at the end of last season.

ies boss Cooper believes patience paid off with the signing of Green and he admitted it took a little bit of polite persuasion to convince the frontman to drop out of Coca-Cola League Two.
"We certainly had to do a little bit of talking," the Kettering manager conceded.
"But I think he realised there is not a lot of difference between League Two and the Blue Square Premier any more.
"We told him our plans and when he had heard everything we had to say, he was happy to come here.
"I have had to be patient but it is pleasing when you put time into getting someone and then it happens.
"He is an experienced head in a young squad and he's a good striker who will get us some goals.
"We have already seen him in training and his touch and movement were very good so hopefully he will prove to be a good signing."
Green's arrival came hot on the heels of the capture of James Jennings who was also at Macclesfield last season.
And Cooper believes there will be at least two more arrivals soon with a goalkeeper on top of the list.
"I know a few people may have been panicking about the lack of signings but I would like to think that we know what we are doing," Cooper added.
"I said last week that the next four signings would be quality players and that's two down.
"We are talking to goalkeepers and Lee Harper is included in that and I would think another striker is a possibility."
Kettering, meanwhile, have added another pre-season friendly to their schedule. They will make the short trip to face Desborough Town at the Waterworks Field on Thursday, July 23 – 24 hours after playing Peterborough at the Elgood's Arena.
