Northampton have secured the signing of former Coventry midfielder Kevin Thornton until the end of the season.
The Irishman signed a monthly contract in January after a successful trial spell but has shown enough in three substitute appearances to persuade manager Ian Sampson to tie him down.
"Kevin has done well and has impressed us," said Sampson.
"He has earned his longer contract.
"He knows he has plenty of hard work ahead of him, but I think he is making good progress and we are delighted he will be staying with us."
