Redskins' Su'a Cravens: Undergoes surgery Tuesday morning

Cravens (knee) underwent surgery Tuesday, Adam Schefter of ESPN reports.

Cravens is expected to be available for the season opener roughly a month from now. Although the injury doesn't appear to be too serious, the Redskins are understandably taking every precaution necessary to ensure a full recovery. Washington will likely hold the 22-year-old out of the team's remaining preseason contests in hopes of avoiding any setbacks.
