The Lions began their 2007 campaign on the road in an interconference game against the Oakland Raiders.  After a scoreless first quarter, Detroit got off to a fast start in the second quarter.  QB Jon Kitna completed a 13-yard TD pass to WR Roy Williams and kicker Jason Hanson connected on a 46-yard field goal.  In the third quarter, the Lions increased its lead with Kitna completing a 16-yard TD pass to rookie WR Calvin Johnson.  The Raiders, however, started to catch up with QB Josh McCown completing a 4-yard TD pass to WR Ronald Curry along with RB LaMont Jordan getting a 12-yard TD run.  In a wild fourth quarter, Hanson gave Detroit a 46-yard field goal, yet the Raiders took the lead with McCown's 7-yard TD pass to FB Justin Griffith.  Fortunately, the Lions hung on to take the lead with Kitna's 32-yard TD pass to WR/PR Shaun McDonald, Hanson kicking a 23-yard field goal, and wrapping it up with RB Tatum Bell getting a 14-yard TD run..
