Luton Town: Hatters seal signing of ex-Derby County defender Mark O’Brien

Luton Town have made former Derby County centre back Mark O’Brien their tenth signing of the summer.

The 23-year-old former Republic of Ireland U21 international can also operate in midfield and has signed a two year deal at Kenilworth Road.

O’Brien is currently with the rest of the Luton squad on their training camp in Portugal and featured as a trialist in the 1-0 friendly victory over Farense on Tuesday night.

His signature means that boss John Still has no shortage of options in the centre of his defence, with Steve McNulty, Luke Wilkinson, Scott Cuthbert and Magnus Okuonghae all in the squad.

After beginning his career at Irish side Cherry Orchard, O’Brien was signed by Derby in 2009 but later in the same year underwent heart surgery to fix a valve problem.

He made a full recovery and went on to make 35 appearances for Derby, while he has also featured in Scotland on loan at Motherwell.

Still watched O’Brien, who was released by County at the end of the season, while he was with Motherwell, in a game where he also saw fellow new signing Stephen O’Donnell.
