Jose Izquierdo could make his debut for his new side, as the left winger has received permission to play for Brighton.
The Colombian professional player has been signed for £13.5m last week, and he received the squad numer 19.
"This has been a very complex deal, but I am absolutely delighted we are finally in a position to confirm it is completed", Brighton boss Chris Hughton said.
Brighton have made a disappointing start to the new Premier League campaign, losing against Manchester City and Leicester.
