The IFA president denied that financial pressures following the recent six-figure payout to former association chief executive Howard Wells are impacting on the negotiations with Worthington.
"The IFA is not struggling," insisted Kennedy.
"There is no link between that (the Wells payout) and Nigel's contract."
Kennedy refused to make any further comment on the Wells issue, citing a confidentially agreement.
The IFA president also revealed that Northern Ireland are likely to take part in a South American tour in late May with Chile set to be among the opposition.
"We have been offered a two-match tour with games on 26 and 29 May with games against Chile and either Uruguay or Paraguay.
"It could a money-spinner for us and the chances of the tour happen are better than 50/50."
A match against the USA in late May has also been mooted although the South American games now seem a more likely prospect.
The IFA are also expected to confirm a friendly for 3 March with Belgium and Austria among countries keen to face Northern Ireland while a game in France against World Cup qualifiers Algeria was also revealed by Kennedy as a possibility.
"Nothing has been ruled out or ruled in at this stage," added the IFA president.
