Walt Harris injured his ACL in Tuesday's practice when he became tangled with receiver Dominique Zeigler along the sideline. Harris stayed down for several minutes after the play and had to be helped by a trainer to a nearby cart. Harris will have surgery on the knee either next week or the week after. The 49ers have not given a prognosis, but we all know that when the ACL is involved there's a very good likelihood that it will be a season-ending injury.

ESPN refuted a report from the Pioneer Press that said Brett Favre had an appointment with Dr. James Andrews on Tuesday and doesn't consider surgery on his partially torn biceps tendon to be imminent, according to a source. Favre discussed surgical and non-surgical options with Andrews last week. Favre, however, remains focused on non-surgical options, including cortisone injections and natural movements like light throwing and bicep curls that might cause the tendon to release naturally, the source told ESPN.

Brett Favre is scheduled to meet Tuesday with noted orthopedist James Andrews in Birmingham, Ala., about surgery to repair a partially torn biceps tendon in his right shoulder, the Pioneer Press has learned. Surgery to release the tendon is considered routine and is expected to be performed by Andrews later this week. Rehabilitation for Favre would be six to eight weeks.

Ravens wide receiver Derrick Mason could miss the start of the team's training camp as he recovers from shoulder surgery. Despite the possibilty of missing time, Mason is optimistic that he'll be ready for the start of the 2009 season. "I guarantee I'll be ready by the first game, that's all I can say," Mason said Sunday, the final day of the team's minicamp. "Everything else, we'll play it by ear." Mason had surgery to repair his scapula and the labrum in his left shoulder in February.

Falcons rookie defensive tackle Peria Jerry suffered a sprained knee during the team's morning practice on Saturday. The team is expected to look at Jerry's knee again on Sunday, but reports on Saturday night indicated a sprain. "That's all we know right now," coach Mike Smith said. In 2008, Jerry underwent arthroscopic surgery to repair a torn meniscus in the same knee he sprained Saturday.

Falcons defensive tackle Peria Jerry, the team's first-round pick, did not practice in the team's evening practice after banging his knee with another player on Saturday morning. Jerry left the field under his own power. "He got banged up," Atlanta coach Mike Smith said. "We don't know anything about it. He bumped knees, and we'll know something by the end of the day. They took him in the training room to ice him."

Seahawks wide receiver Nate Burleson is practicing just eight months after undergoing reconstructive knee surgery. "I feel like I always have, like I'm the same player," Burleson said after he ran pass routes effortlessly. He took part in three days of organized drills on the field with quarterback Matt Hasselbeck, the new coaching staff and the rest of the Seahawks. "Of course, I'm not going to be 100 percent yet," Burleson said, wearing a black brace over the knee. "The last couple of days, I've got to be honest, there was some doubt in my mind, but right now I don't feel my knee hurting. This week has proved to me the rehab is working."

Vikings rookie wide receiver Percy Harvin is back to full health and resumed workouts Tuesday, according to his agent, Joel Segal. Harvin, the 22nd overall pick by Minnesota, was hospitalized in Atlanta on Thursday when he fell ill while en route to the Vikings' minicamp.
