Mwepu joined Brighton from Salzburg in a reported £18million (€21m) deal in July 2021 and made 27 appearances for the Premier League side in all competitions.
He played in six of Albion s opening eight top-flight matches in this campaign, including the 2-1 win over Manchester United on the opening weekend, starting two of those.
When announcing his retirement three months ago, Brighton said Mwepu was at an extremely high risk of suffering a potentially fatal cardiac event if he continued playing.
