49ers-Ravens Injury Report: Dante Pettis, Dee Ford don’t practice; George Kittle, Joe Staley limited

The San Francisco 49ers are preparing for their Week 13 contest against the Baltimore Ravens on Sunday at M&T Bank Stadium in Baltimore, Maryland.

The media was not allowed to observe Thursday's practice because of the Thanksgiving holiday.

WR Dante Pettis reportedly left practice on Wednesday with what looked to be a left knee injury.
