FOXBOROUGH, Mass. - New England Patriots quarterback Tom Brady sustained both a torn ACL and MCL in his left knee on Sunday, but medical tests showed no damage to other knee ligaments and no torn cartilage, the Boston Globe reported Wednesday.

Brady will probably have surgery in a month, the Globe said, and will need 6-9 months of recovery and rehabilitation.

Brady visited his Patriots teammates Wednesday, three days after suffering a season-ending knee injury.

Wide receiver Randy Moss said the quarterback and reigning NFL MVP was at Gillette Stadium and the visit was “uplifting.” Brady was shown walking out of the stadium with a limp but no crutches on a video aired on WHDH-TV.

“We saw Tom today,” Moss said in a national conference call. “I am not sure how much longer we are going to see him, but he is here today and has been uplifting and keeping a positive attitude. I think that goes a long way with not only him but the team as well.”

The Boston Globe reported on its Web site Wednesday that Brady suffered a torn anterior cruciate ligament and a torn medial collateral ligament in his left knee in Sunday’s season opener. The team has not given details of the injury and a spokesman said it declined to comment on the report.

The report cited NFL sources and said medical tests indicated no damage to other knee ligaments and no torn cartilage. It also said Brady probably would have surgery in a month and face a recovery and rehabilitation period of six to nine months if there are no complications.

In comments to reporters on Monday, Tuesday and Wednesday, Belichick did not specify what was wrong with the knee. But the play on which Brady was hurt, his reaction and the prognosis all point toward a torn anterior cruciate ligament.

He was injured on a play that ended with 7:27 left in the first quarter of the Patriots’ 17-10 win over Kansas City. He was hit on the knee by safety Bernard Pollard, who had scrambled toward him after being knocked down by blocker Sammy Morris. Brady was stepping forward to throw a complete pass to Moss when he was hit and fell to the ground.

Moss said Brady was “upbeat” during his visit.

“He is still the same old Tom Brady,” Moss said. “I think that is what a lot (of) people don’t really understand. A lot of times when guys get hurt, you might not see him around the locker room for months at a time.”

But Brady was there Wednesday, a day on which his team practiced to face the New York Jets on the road Sunday.

“You expect a guy to really be down on himself,” Moss said. “I think he was more down last Sunday. Just from a few conversations and text messages, he is still positive. That is what you can hope for in a guy like Tom.”
