Following toiday's mid-morning walk-through, San Francisco 49ers head coach Mike Nolan announced the rotation for Saturday's game against the Green Bay Packers – basically the same as last week.

Quarterback J.T. O'Sullivan will start for the second week in a row, followed by Alex Smith and then Shaun Hill.

The first units are expected to play most of the first half, although Nolan did say he'd let the game dictate the exact plays.

Wide receiver Isaac Bruce will play in the game, but probably only a series.

Running back Frank Gore was another starter who Nolan said probably would not play as long as the other starters.
