Jean-Philippe Gbamin is set for another spell on the sidelines after undergoing a surgery on an injury suffered in August.
The Cote d’Ivoire international who joined the Premier League side from Mainz as Idrissa Gueye’s replacement will be until January 2020.
Having featured against Crystal Palace and Watford, Gbamin damaged a quadriceps muscle in training – six days before Everton’s 2-0 defeat at Aston Villa.
He was back in light training but suffered another setback that required an operation in France on Tuesday.
“Everton Football Club can confirm that Jean-Philippe Gbamin has undergone surgery on a tendon injury in his right quadriceps muscle, which will keep the midfielder out of action for around three months,” a statement from the club read.
