Portadown have confirmed the signing of former Luton Town midfielder Dominic Dos Santos Martins after impressing during a trial period at Shamrock Park.

Martins came through the youth ranks at Luton and was named on the bench for Premier League fixtures against Bournemouth and Nottingham Forest during the 2023/24 season.

The 20-year-old was a regular presence for the club’s U21s, helping the Hatters reach the Premier League Cup last-16 in 2025 – Martins was named captain in group matches against Reading and Brighton.

Martins joined Hitchin Town on loan in March 2025 before departing Luton later that year and has enjoyed further senior spells at Morpeth Town and Blyth Town.

After taking a closer look at Martins during their 2-1 behind-closed-doors friendly win over League of Ireland outfit Bohemians earlier this month, Portadown have now opted to sign the midfielder on a permanent basis.

"Dominic is a player that we have been monitoring and had the opportunity to see him up close as a trialist in our recent pre season friendly against Bohemians,” said David Douglas, Portadown’s Head of Recruitment and Football Operations, on the club’s website. “He is primarily a defensive midfielder who is positionally aware and has the technical ability and passing range to create opportunities for forwards.

"He showed very well against a really good Bohemians team and we look forward to seeing him in a Portadown shirt this season.”
