An already thin 49ers secondary got thinner on Sunday night, as both Josh Norman (chest) and K'Waun Williams (calf) were knocked out of the Week 3 loss to the Green Bay Packers. Coach Kyle Shanahan spoke to reporters after the defeat, and updated the status of the two defensive backs going forward.
Shanahan wasn't sure about the severity of Norman's injury, and the two likely will be evaluated this week.
Jason Verrett was lost in Week 1 with a torn ACL, and Emmanuel Moseley started Sunday's game despite being hobbled by a knee issue.

Williams already was dealing with a calf injury, and was taken out of the game early as it continued to bother him. Williams also had a single tackle before leaving the game.
Dontae Johnson did what he could to spell both of the injured cornerbacks, as rookie Ambry Thomas and veteran Dre Kirkpatrick weren't active for the game. Johnson did suffer a shoulder stinger according to Shanahan, but did return to the game.
