Eintracht Frankfurt's Mexico international Marco Fabian is set to undergo back surgery in the United States, with the club hopeful that he can return to full training in the New Year.

Fabian, 28, was initially set for a two-month spell on the sidelines while undergoing treatment for lower back problems.

However, both Frankurt and the midfielder have decided that surgery is needed, meaning he will sit out the rest of 2017.

"Marco Fabian is to undergo surgery in Houston, Texas. That hurts," Frankfurt sporting executive Fredi Bobic told reporters at a news conference on Thursday. "The treatment did not work.

"We expect him to be sidelined for at least three months if everything goes as planned. We hope that he will be back with the team in January.

"He wants to play football again, and he promised me he would come back stronger."

Fabian missed parts of last season with lower back problems, which returned when he resumed club training following his involvement at the Confederations Cup in Russia.

Frankfurt are on the verge of completing a free transfer move for Kevin-Prince Boateng to replace him.

The 30-year-old Berlin-born midfielder has terminated his contract with La Liga side Las Palmas, and Bobic said: "He is currently on his way to Frankfurt.

"We would like to sign him, but it's not done yet. There will be a medical, there are other things still left to be sorted out and the player first has to arrive here in Frankfurt."

Boateng last played in Germany at Schalke from 2013 until 2015.
