FSV Mainz 05 have confirmed that midfielder Eric Martel is facing time on the sidelines after suffering a knee ligament injury. The club said in a statement that the summer signing could be out indefinitely.

According to the update, Martel injured the medial collateral ligament in his right knee. That diagnosis points to a significant setback for the player early in his time with Mainz, although the club has not indicated a firm timetable for his return.

The news is a blow for Mainz as they assess their midfield options going forward. Losing a recent arrival for an unspecified period creates uncertainty around selection and depth, especially when a player is still settling into a new team.

For now, the focus will be on Martel's recovery and the club's next medical assessments. Until Mainz provide another update, his absence remains open-ended after this right knee ligament injury.
