The Oakland Raiders hit the field for their first full practice in preparation for this Sunday’s 2015 regular season Week 4 matchup with the Chicago Bears at Soldier Field. The last time the Raiders faced the Bears in Chicago in the regular season, a Paul Edinger field goal in the waning moments was the difference in a Bears victory. Twelve years later the Raiders are on the heels of back-to-back victories secured in the waning moments of each and are looking for their first two-game road winning streak since 2011. The Raiders are also seeking their first three-game winning streak since 2011.
