ROME (Reuters) - Juventus full back Dani Alves fractured his leg during Sunday's Serie A match against Genoa, the Italian champions said on their website.

Brazilian Alves, 33, moved to Italian champions Juve this term on a two-year contract after eight seasons with Barcelona.

Juventus defender Leonardo Bonucci was substituted due to a thigh injury during the 3-1 loss at Genoa and will undergo tests to determine the extent of the problem.

Juve, bidding for a sixth Serie A title in a row, lead the standings by four points from AS Roma and AC Milan.
