Brock Purdy overcame a scare at 49ers training camp and connected with Jordan Watkins on a deep pass to highlight Tuesday’s session.

Keep in mind, several players did not participate in today's practice, players such as rookie first-round pick Mykel Williams, who injured his ankle on Monday, according to the team. Williams played through an ankle injury all of last season. It's unclear if he has injured the same ankle. More on him in a minute.

During a press conference after Sunday’s practice, San Francisco head coach Kyle Shanahan said it is “always scary” to see a player leave the field on a stretcher but said Jackson was conscious and had movement in all extremities by the time he was taken away.

Tarron Jackson, a defensive end seeking a roster spot with the 49ers, was placed on a backboard and hospitalized after a hard collision during Sunday's practice.

Tuesday’s practice leads into the final day of a four-day stretch on Wednesday. Practice begins at 9:15 a.m. Arrowhead Time. Defensive coordinator Steve Spagnuolo will address the media following the practice as linebackers sign autographs.
