Kyle Shanahan expects Chase Young to play a large role for the San Francisco 49ers this Sunday after the team traded for the defensive end during their bye week.

"I think he's going to jump in right away," Shanahan said. "First time we saw him was Monday. We had a slight small practice, and we'll see him out there [Wednesday] really for a real practice. Hopefully he'll pick up the stuff throughout the week and going to be out there a good bit on Sunday."

Asked whether he hopes to have a "big role" for Young, Shanahan said, "Yes, hope so."
