The Chargers, a team that planned to be driven by running the football, have already seen Najee Harris go down with a season-ending injury and first-round pick Omarion Hampton land on injured reserve. With Haskins now going down, the team has lost its top three running backs.

Veteran Najee Harris dealt with an off-field injury that caused him to miss training camp. Upon returning, Harris would then tear his Achilles just three games into the year. Rookie Omarion Hampton emerged as the team's primary back, but then he suffered an ankle sprain that landed him on IR.

In a season that has been filled with ups and downs, one of the bright spots has been Oronde Gadsden II, the rookie tight end out of Syracuse. Gadsden has made waves with his talent and work ethic, which Harbaugh recognized early in training camp.

The Chargers signed running back Trayveon Williams to the practice squad, a quiet move tucked into a list of roster moves announced Tuesday. Williams is a veteran depth option who recently spent a big chunk of time with the Cincinnati Bengals.
