Torn ACL...not a good thing for Brewers fans.

The Milwaukee Journal-Sentinel reports that Yovani Gallardo has a torn ACL.

An examination of Gallardo in Milwaukee on Friday morning revealed the injury, which Gallardo suffered in a collision with Reed Johnson on Thursday. The team will wait until swelling subsides to determine if he needs surgery, but there's a good chance he'll miss the rest of the season. Dave Bush will be recalled and replace him in the rotation.
