Chaz Schilens (foot) will make his season debut on Sunday against the Jets and may start.
Going to the actual article it doesn't sound to me like it's updated information, nor confirmation that Schilens plays this week.
News: The San Francisco Chronicle reports that Oakland WR Chaz Schilens (foot) suffered a setback in practice on Friday and now might not be able to make his season debut Week 7 against the Jets. He got a little sore today," coach Tom Cable said. "We don't know if there's anything wrong. Right, at this point, we may know something this afternoon or tomorrow, exactly what our plan will be, but a little sore today. So we shut him down." Schilens is listed as questionable for the contest.
I didn't take this as him having re-injured the foot, more that he had some soreness so they sat him, hopefully to be ready for Sunday.
