Kelley carried the ball seven times for 21 yards to go along with one fumble in Thursday's 34-28 overtime loss to the Chiefs.
Kelley's fumble could have long-term ramifications considering the goal-line gaffe was simply an egregious mistake in a pivotal situation. While the second-year back has seen 17 carries over the past two weeks with the Chargers carefully managing Austin Ekeler's ankle injury, Kelley has struggled with the usage, averaging 3.2 yards per carry over that span. It's entirely possible Larry Rountree, who was a healthy inactive Thursday, could push for additional playing time in light of Kelley's latest miscue.
