Jennings caught two of five targets for 19 yards in Thursday's 20-17 loss to Tennessee.
Jennings saw his usual allotment of offensive snaps (46 percent), but was unable to replicate last week's trip to the end zone. The 23-year-old would have finished with three receptions for the third straight game if he didn't drop a pass that hit him right in the hands during a crucial stalled drive in the fourth quarter. Jennings has settled into a low-usage role as the 49ers' No. 3 wideout heading into a Week 17 matchup against the Texans.
