When is Brock Purdy coming back? What about a trade?

Kyle and Chris discuss Brock Purdy's toe injury and when the best time to bring him back would be. Does he need to be fully healthy to unseat Mac Jones, will the 49ers be able to tolerate a poor game like he had against the Jaguars? They also discuss the idea of making a trade before the NFL trade deadline in two weeks and what type of trade they would make.
