Brighton winger Billy Arce has returned from his loan spell at Spanish Segunda Division club Extremadura UD, while under-23 defender Josh Kerr has joined Derry City on a six-month deal.
Arce, 20, signed for the Seagulls during August 2018 from Ecuadorian side CSD Independiente Del Valle, and moved straight to Spain on a temporary deal, making four appearances including the full match of the Copa Del Rey tie against Alcorcon.
Meanwhile, 20-year-old centre-back Kerr, signed from Celtic in May 2017, has linked up with the League of Ireland club for the rest of the campaign.
Under-23 coach Simon Rusk said on the Brighton website: "This is a good loan move for Josh, and one that will allow him to play first-team football on a regular basis. We will keep a close eye on his progress."
The centre-back made nine league appearances in Albion's Premier League 2 Division 2 promotion-winning campaign last season, scoring once in a 4-2 win over Fulham.
Brighton also confirmed under-23s midfielder Steven Alzate had returned to the club from Swindon after suffering a lower back injury.
The 20-year-old made 26 appearances and scored three goals during his time on loan at the County Ground.
