Eintracht Frankfurt defender Jesus Vallejo, on loan from Real Madrid, may not play again this season after suffering a tendon injury, the club have said.

Vallejo, 20, is in the final weeks of his loan spell at the Bundesliga club, for whom he has made 25 appearances.

In a statement on their official website, Eintracht said: "The Spaniard sustained a muscle tendon injury in his left thigh. It is not clear whether he can return to the pitch this season."

Sporting director Bruno Hubner said the injury was "another setback during the important run-in" and added: "Of course it's difficult to replace Jesus, but we wish him a full and speedy recovery and it's our hope that we can see him in the Frankfurt jersey again."

Eintracht are open to extending Vallejo's loan deal for another season, although a space in the Madrid senior squad could open up with Pepe, 34, set to leave in the summer.
