However, Lance suffered a season-ending injury in Week 2. The situation meant Jimmy Garoppolo would return to the starting lineup.Then, in Week 13 against the Miami Dolphins, Garoppolo suffered a foot problem that will likely end his season. This left the Niners with two options going into the playoffs: signing a free agent as a temporary replacement until the end of the season or relying on the final pick in the NFL draft.FootBasket™.com@FootBasketThe Brock Purdy story 35056The Brock Purdy story 🔥 https://t.co/7lKZmHK45tThe San Francisco 49ers gave Brock Purdy his first NFL start against Tom Brady and the Tampa Bay Buccaneers.
