The 49ers' injury woes continued on Sunday, as middle linebacker Fred Warner left in the third quarter against the Washington Football Team with an apparent shoulder injury.
After being in on a stop, Warner came off appearing to point the 49ers' trainers toward his collarbone.
He went into the blue medical tent on the 49ers' sideline after coming off the field.
The 49ers later announced that Warner is being evaluated for a head injury.
Warner had five total tackles in Sunday's game prior to his injury.
