ALLEN PARK — Coach Jim Schwartz said today that he will wait until Friday to name a starting quarterback for Saturday’s third preseason game against Indianapolis at Ford Field. Daunte Culpepper started the opener and rookie Matthew Stafford started a week ago. The starter for Saturday will not necessarily be the regular season starter.

Schwartz also would not say how long each quarterback will play. He did say the receivers will rotate in and out of the game. That way both Stafford and Culpepper will have a chance to throw to top receivers Calvin Johnson and Bryant Johnson and rookie tight end Brandon Pettigrew. It will be the first preseason action for all three of them.
