Although Matt Cassel will start Friday's preseason opener for the Vikings, rookie Teddy Bridgewater will get snaps with the starters against the Raiders, coach Mike Zimmer told 1500ESPN.com.
"When the lights come on, it's a different deal," Zimmer said. "It will be good for [Bridgewater] and how he reacts to seeing defenses that he hasn't seen very much of. How he has to readjust the blitz, how he has to get the ball out and make the right calls; how he plays under pressure. I anticipate he's going to play very well."
