McKeown is in line to make his Portadown debut on Saturday

Defender McKeown had agreed a two-year contract with Ports boss Ronnie McFall earlier this month but the deal was held up by haggling over the fee.

However, the clubs agreed terms on Tuesday and McKeown will be in Portadown's squad for Saturday's Carnegie League game at Ballymena.

McKeown's contract at Lisburn Distillery had been due to run out at the end of this season.
