EDGE Analysis

Saubert played 23 offensive snaps and caught all three of his targets for 30 yards in Week 17, but he's sidelined to start Week 18 prep due to a knee injury. The extent of the injury remains unclear, but the backup tight end will have two more chances to practice before the team needs to make a decision on his status for Sunday's matchup against the Chargers.
