Brewers' pitcher Yovani Gallardo has torn cartilage in his knee and will miss four weeks, the team announced Sunday.

Gallardo will undergo arthroscopic surgery Tuesday to repair a torn lateral meniscus.

Gallardo almost certainly will begin the season on the disabled list for the Brewers, who were counting on the righthander to be a member of their starting rotation.
