Portadown announced on Tuesday that a deal to sign Joe Gorman "has not been concluded".
The decision came following a backlash from the club's fans when the 27-year-old Dubliner's signing from Galway United was announced on Saturday.
In 2014, then aged 19 and playing for Scottish side Inverness, Gorman was suspended by the club after posting a sectarian tweet.

"Ross Kemp in Belfast talking about the Troubles. Wouldn’t you just love to open up on all them Orangemen," Gorman said in a tweet which was later deleted.
On Tuesday evening, Portadown tweeted: "Update on Joe Gorman signing.
"After further discussions this deal has not been concluded. We wish Joe all the best for his future career."
Portadown are currently second from bottom of the NIFL Premiership with 12 points from 21 games.
Gorman played 11 times for Galway last season. He previously has spells with Longford, Cliftonville, Blyth Spartans and Clyde, among others.
