Franck Ribery was seriously wounded and replaced by Valentin Eysseric during the first half of Lazio-Fiorentina.
The French striker started for La Viola against Lazio at the Stadio Olimpico, but Cesare Prandelli was forced to replace him after just 37 minutes.
According to Sky Sport, the Frenchman has suffered a muscle injury and his circumstances will be assessed in the coming hours. Eysseric substituted the former Bayern Munich star for Christian Kouamé, who remained on the bench.
The Ivorian has emerged as a concrete transfer target for Verona and Torino, who are interested in signing the agreement in January, according to reports in Italy.
