The San Francisco 49ers have asked Trey Lance to play the role of Aaron Rodgers in scout team practices this week.

"We need Trey to be very aggressive, let it rip," Kyle Shanahan said. "Hopefully if he does make some mistakes in practice, our defense will catch it and make him pay. But we need him to be aggressive in everything he does because Aaron doesn't miss many of those opportunities when they're presented to him."

Jimmy Garoppolo is set to play through a thumb and shoulder injury in Saturday's divisional playoff contest.

Lance has spent time during his rookie campaign attempting to imitate different quarterbacks during practice, from Kyler Murray to Kirk Cousins and now Rodgers. The rookie has said there is a benefit in his development from studying other quarterbacks in his practice role.
