In Hour 3, John Dickinson and Greg Silver shift to the 49ers to break down the latest developments in Day 2 of camp, including an injury scare to rookie Romello Height. The 49ers are looking to bolster their defense, but they're still thin on the line, and injuries are a concern. The team is counting on young players to step up. Meanwhile, the offense is looking strong, with Mike Evans making a big impression in his first day of practice. The team's quarterback, Brock Purdy, is also feeling confident, having learned from his experiences in previous seasons.
