Purdy limited Tuesday

49ers QB Brock Purdy (oblique) was listed as a limited participant in what was a light practice on Tuesday. HC Kyle Shanahan wouldn't say for sure whether Purdy will start Thursday night's game vs. the Seahawks but did say that the oblique injury is more of a pain-tolerance issue. Purdy told the media that he's able to run but hasn't tried to throw since Sunday. We'll get another update on his status tomorrow. QB Josh Johnson would start against Seattle if Purdy can't.
