Packers' Zayne Anderson: Sustains knee injury

Anderson left Saturday's preseason game against the Jets early due to a knee injury, Rob Demovsky of ESPN.com reports.

Anderson appears to be done for the day, though the severity of his knee injury remains undisclosed. The 28-year-old is expected to kick off the regular season as one of Green Bay's top backup safeties behind Evan Williams and Xavier McKinney (calf).
