The Boston Herald reported that New England quarterback Tom Brady has undergone two more procedures to clean out infection on his surgically repaired knee.

The newspaper said Brady is on a six-week course of intravenous antibiotics and will continue to have follow-up exams at the clinic in Los Angeles where he had surgery.

Brady confirmed for the first time last weekend that he'd undergone two operations on his injured left knee. But the Herald , citing an unnamed source familiar with his treatment, says he's had two more since then because of infection.

l Running backs Sammy Morris and LaMont Jordan were listed as doubtful for Sunday's game, and Laurence Maroney is out for the season with a shoulder injury. That leaves Kevin Faulk , primarily a third-down back, rookie free agent BenJarvus Green-Ellis and fullback Heath Evans .

COLTS: A staph infection in a bursa sac in Peyton Manning 's left knee led to the surgery that kept him out of much of training camp.

SEAHAWKS: Quarterback Matt Hasselbeck (bulginig disc in back) will again be watching from the sidelines Sunday. Receiver Deion Branch is likely to join him with an injured foot.

GIANTS: Receiver Plaxico Burress was fined $45,000 by the NFL for verbally abusing an official and tossing a ball into the stands during last weekend's win.

STEELERS: Running back Willie Parker didn't practice Friday because of ongoing problems with his sprained left knee and is unlikely to play Sunday against the Giants. Wide receiver Santonio Holmes also was held out of practice and will be deactivated after city police stopped his car and smelled burning marijuana Thursday.

SAINTS: Veterans Deuce McAllister and Will Smith reportedly are among several players who have violated the NFL steroids policy.
