Brighton striker Aaron Connolly has joined Middlesbrough on-loan to the end of the season.
The Republic of Ireland international is Boro's first signing of the January transfer window.
Middlesbrough boss Chris Wilder said he is delighted about his side's first signing of the January transfer window.
He told the club's website: "I'm delighted. It's an area of the pitch we need to improve in terms of competition for places.
"He's a young player, he's played in the Premier League a number of times and he's from a technical football club. He's also played for his country.
"He gives us pace, can finish at the top of the pitch and gives us competition for the players around him."
