Yahoo! Sports' Michael Silver is reporting that Tom Brady might be out for the year with ligament damage to his knee.
New England Patriots quarterback Tom Brady is expected to miss the rest of the 2008 season with what two sources described as a severe injury to his left knee, suffered in the first quarter of the Pats’ 17-10 victory over the Kansas City Chiefs at Gillette Stadium Sunday. While New England coach Bill Belichick said in his postgame press conference that he had no update on the status of Brady’s injury, a source close to the quarterback indicated it involved serious damage to the knee. That could include a torn anterior cruciate ligament and perhaps other ligament and cartilage damage. “It’s bad,” a team source said. “We’re going to have to play without him.”
While the news from "sources" sounds serious, I'd hold off jumping from the bridge until the official report comes out.
