Rountree lost a combined two yards on his only target and carry in Sunday's 20-17 loss to the Cowboys.
One week after recording eight carries for 27 yards, the rookie sixth-round pick took a back seat to Justin Jackson from a yardage perspective (29 total yards) and snaps (16 to 10 in favor of Jackson). The snap totals at least reflect a close competition for the backup role behind Austin Ekeler, but the extra usage of both Rountree and Jackson could essentially boil down to whether or not the Chargers are playing from behind.
