Jackson (undisclosed) was spotted practicing Wednesday, Jeff Zrebiec of The Athletic reports.
Jackson was held out of practice Monday after a 27-20 loss to the Chiefs on Thursday, and while he may be listed on the Week 2 injury report, his presence on the field Wednesday suggests that he'll be ready to play this Sunday against the Raiders. He played every snap in the season opener, piling up 273 passing yards and 122 rushing yards against the Kansas City defense.
