Martin (hamstring) is listed as questionable ahead of Sunday's matchup with the Giants, John Keim of ESPN.com reports.
Martin appears to have sustained a hamstring injury during Friday's practice that's put his Week 2 availability in jeopardy. The second-year safety is coming off an impressive Week 1 performance in which he recorded nine total tackles on 56 defensive snaps. However, if he's unable to go Sunday, expect Jeremy Reaves to work as Washington's top free safety.
