The San Francisco 49ers released their depth chart for Week 4 against the Arizona Cardinals and there is a noticeable, and expected change. The team placed defensive lineman Tank Carradine on injured reserve with a high ankle sprain, and have replaced him on the depth chart with rookie Solomon Thomas. The new depth chart includes Thomas as the right defensive end.
A high ankle sprain is usually not season-ending, which suggests Carradine is a strong candidate to be returned from injured reserve in two months. A team has to keep him there for eight weeks.
