The San Francisco 49ers offensive starting lineup will look very different on Sunday.
There will be changes at quarterback, tight end, running back, and perhaps at wide receiver and on the offensive line.
Here's the summary of what's gone down since the 49ers last played against the St. Louis Rams on Nov.1:
Blaine Gabbert has been named the starting quarterback for Colin Kaepernick. Pierre Thomas and Shaun Draughn were added in the backfield to help offset injuries to Carlos Hyde (foot), Reggie Bush (knee, placed on Injured Reserve) and Mike Davis (hand surgery).
