Chelsea have confirmed that Michael Hector and Lucas Piazon have returned to the club with immediate effect.
The duo had spent much of the ongoing campaign on loan with Championship outfit Reading.
However, with the Royals in 15th position and having very little left to play for, the duo have linked back up with their Premier League employers.
Although they will train with the first team at the club's Cobham base, neither player is permitted to feature in any of Chelsea's remaining four league encounters.
