In other injury news, Brett Favre is listed on the injury report as probable with a sore knee and ankle, suffered in the 49er game.
"It's a high ankle sprain," Sherman said. "He didn't complain about it after the game.
Favre received treatment for the ankle Monday.
Nose tackle Gilbert Brown, last seen breaking Jeff Garcia's slide on the Packer sideline, sat out practice Wednesday and continues to be bothered by a swollen ankle. The injury was aggravated by the flight to and from California," Sherman said.
"His ankle was not better but maybe a little bit worse on Monday, which is ironic considering hte didn't play," Sherman said. "But the flight certainly didn't help him."
