Chargers release RB Marion Grice

SAN DIEGO -- The San Diego Chargers continued to churn the roster as they prepares for the regular-season opener at Arizona.

The Chargers released sixth-round selection Marion Grice on Monday, according to a source. If the Arizona State product clears waivers, he’ll likely be added to the team’s practice squad. The Chargers have one remaining spot on the practice squad, as it stands now.

Grice was released in favor of undrafted rookie free-agent running back Branden Oliver, who remains on the team’s active roster as the fourth running back behind Ryan Mathews, Danny Woodhead and Donald Brown.

The move opens up a spot on San Diego’s active roster. The Chargers are thin at defensive line, and could be looking for a player to add depth and experience up front like 31-year-old veteran Kevin Vickerson, released by the Denver Broncos during final roster cuts.

San Diego will hold a practice at Chargers Park at 1 p.m. ET on Monday.
