Juventus defender Federico Gatti suffered a fracture of his calf bone during Saturday's 1-0 Serie A win over Genoa, his club said in a statement.
Italian media reports said Gatti could be out for a month after he was forced off the field in the first half after a clash with Genoa striker Andrea Pinamonti, who missed the ball and inadvertently kicked Gatti's leg.
"The tests revealed the presence of a compound fracture to the diaphysis of the fibula," Juventus said on Monday.
Pinamonti apologised for the incident on social media.
"I am so sorry for your injury, I wish you a speedy recovery and that you can return to the field as soon as possible," he wrote on Instagram.
Gatti, 26, said he will do everything he can to make a quick return as fifth-placed Juventus continue their battle to qualify for the Champions League with a top four finish.
"I will try to be as close as possible to my teammates at this very important time of the season," Gatti wrote in an Instagram story.
Juventus, who are just a point below fourth-placed Bologna, visit Roma on Sunday.
