Justin Smith is expected to retire from the NFL at the age of 35.

Smith has considered retirement over the past several seasons.

“Out of respect to Justin, I’ve told him, I will not try to talk him into anything,” 49ers coach Jim Tomsula said recently at the NFL Scouting Combine. “And I will not try to talk him out of anything. He has earned the right to make his decision on his terms. We said that for the last three or four years.”

Smith is a five-time Pro Bowl selection and was part of the foundation of the San Francisco 49ers' defense.
