Brighton have signed Ingolstadt fullback Markus Suttner.
He has signed a three-year deal with the Seagulls and has joined up with his new side at their training camp in the Austrian Alps.
"Markus is someone we have been aware of for some time," Hughton told the club's official website.
"I am pleased we have managed to complete the transfer at this stage, and he is now able to join us for the second half of the week.
"He has a great level of experience internationally, and in the top divisions in both his native Austria and Germany, where he has played the last two seasons with Ingolstadt, and that experience will serve us well.
"He will add competition at the back on the left side of defence, and I'm now looking forward to working with him."
Suttner said: "In this stage of my career, it's perfect to play in the Premier League, and the challenge for Brighton is a similar one to the one I first encountered with Ingolstadt.
"For me, the chance to play in the Premier League is one of the best options for any player and I'm very happy to be here.
"It's a very good move at this time in my career, and I don't have words to describe how happy I am to have signed the contract."
