Rountree played all five of his snaps on special teams in Sunday's 41-22 win over the Bengals.
Rountree is currently operating as the Chargers' No. 4 running back, working behind starter Austin Ekeler and top backups Justin Jackson and Joshua Kelley. Barring absences from one or more of the players ahead of him, the 22-year-old rookie should remain far off the fantasy radar heading into the Chargers' Week 14 game against the Giants.
