O’Brien trains with Hatters


O’Brien was released by the Rams this summer, after spending time on loan last season at Scottish Premiership side Motherwell where he made 21 appearances.

The 22-year-old is with the Hatters on their pre-season training camp in Portugal and boss John Still told the Luton News, Herald & Post: “Mark has come out with us and I knew Mark, I’d seen him play before at Derby and Motherwell.

“When we found out that he hadn’t been retained at Derby, we spoke to someone at Derby who recommended him highly.

“I said ‘why not come and do a little bit of work with us?’ We’ll have a good look at him, he can have a good look at us and we’ll decide from there.”
