Jeff Cumberland

San Diego Chargers running back Branden Oliver was taken off the field on a cart late in the first half of Sunday's preseason tilt with the Minnesota Vikings.

The Chargers announced it was an Achilles injury for Oliver and he won't return to the game. NFL Media Insider Ian Rapoport reports, via a source informed, the running back tore his Achilles and will miss the season.

The Chargers lost tight end Jeff Cumberland to an Achilles injury last week. The devastating injury could have struck twice for the Bolts.

Oliver was looking like the backup to Melvin Gordon with Danny Woodhead the third down and pass-catching specialist. Dreamius Smith and Derek Watt are next up on the Chargers depth chart so it's not out of the question the team looks to add at this position for some insurance behind Gordon.
