Jennings secured two of nine targets for 31 yards in the 49ers' 12-6 loss to the Rams on Thursday night.
Just four days after bringing in seven of eight targets -- a pair of touchdown grabs among them -- against the Bears, Jennings saw a team-high target total in Thursday's rainy conditions but was highly inefficient. The veteran wideout entered Thursday with a solid 73.1 percent catch rate on the season, and his struggles led to his lowest yardage total since Week 6. Jennings will aim to bounce back against a talented Dolphins secondary in a Week 16 road interconference battle on Sunday, Dec. 22.
