Lance in line for Week 18 start?

49ers HC Kyle Shanahan said after Sunday's win over the Texans that QB Jimmy Garoppolo will start next weekend's regular-season finale if his thumb is back to 100%. But he also admitted that it'll be tough for Garoppolo to get to 100% by next Sunday. So it sure sounds like QB Trey Lance is the favorite to start vs. the Rams. The rookie disappointed with just 31 scoreless rushing yards today but delivered with 249 yards and 2 TDs passing.
