The Facts: Rosenfels opened the second half of today's game against the Vikings after Matt Schaub suffered what appeared to be an injured knee.

Diehards Line:While Schaub remains on the sideline, and he was responsible for three turnovers in the first half, the team is saying the left knee is the reason for the change. Schaub finished the day with 139 passing yards, an interception and a pair of fumble. Rosenfels tossed a TD to David Anderson on his first series.
