Martin Truex Jr. and Kevin Harvick are in the Chase for the Sprint Cup's Round of 12 via victories, leaving plenty of anxiety for the other 14 drivers entering Sunday's Citizen Soldier 400 at Dover International Speedway. It's the final race of the Round of 16; four drivers will be eliminated from the Chase.

Anything could happen at the Monster Mile. Just look at last season when Jimmie Johnson, who has a track-record 10 wins, came into the race with a 27-point edge above the cutoff line. Then, disaster struck: The six-time champion's car had a broken a rear axle seal, forcing him to finish 41st and eliminating him from the Chase.
