Jeremy Shockey (groin) and Marques Colston (thumb surgery) were both limited participants in Saints practice Wednesday.Sean Payton says both could be ready for the Raiders. "I was pleased with what I saw...and I saw more than I expected to see," he said. "Both of them...moved around pretty good. We'll see tomorrow how they feel, especially when it comes to Jeremy. But Marques looked good." It sounds like Colston is fairly likely to play, which is a nice surprise. Shockey is more questionable.
