The St. Louis Rams got some bad news on Friday. Rookie defensive tackle Michael Brockers does indeed have a high ankle sprain on his right ankle, an injury suffered in Thursday night's fourth and final preseason game against the Ravens.

Brockers had an MRI on Friday morning that confirmed the injury, according to the Post-Dispatch. The 14th overall pick in the 2012 NFL Draft is wearing a cast on his leg. It is the same injury that put Sam Bradford on the shelf last season, and it is expected to keep Brockers out a month.

The LSU product had locked down a starting job next to Kendall Langford. Depth was already a real concern for the Rams, and it will be even more so with Brockers on the shelf. General manager Les Snead said that the team will be looking for help at the position as team make their final round of roster cuts on Friday.

Typically, teams elect to sit their starters in the final preseason game. Head coach Jeff Fisher felt that his starters needed more work to get ready for the season.
