It was De' Vondre Campbell who started all year in place of injured Greenlaw who was activated and started last night. He eventually left the game (3rd quarter I think) due to undisclosed "soreness." Cambell had already walked off the field so next man up.
Greenland is a heck of a linebacker but allot of injuries has interfered with what could be a great career.
On another note, Purdy has not looked pretty this year. I realize allot of weapons have been missing but his passing has been erratic, when the weather is bad, he looks awful. I believe he's got a contract due this off season and it will be interesting in 49er land.
