The 28-year-old joined Genoa from Hamburg in 2014 and has made 78 appearances in Serie A, scoring three goals.
He could be in line to make his debut when Juve return from their mid-season break at home to Bologna on Sunday.
Juve were heavily linked with bringing Axel Witsel to Turin from Zenit during the January transfer window, but the Belgium international has opted instead for a move to the Chinese Super League with Tianjin Quanjian reported to be his likely destination.
