The Boston Globe is reporting New England Patriots QB Tom Brady suffered tears to the anterior-cruciate and medial-collateral ligaments in his left knee when Kansas City Chiefs S Bernard Pollard hit him Sunday.

The story, citing unnamed sources, states Brady suffered no additional damage to other ligaments or cartilage on the buckling hit.

Boston Globe reporter Shira Springer goes on to describe the normal course of action for such injuries. The MCL is given four to six weeks to heal before the ACL is reconstructed. Recovery takes six to nine months.
