The short-track tour continues for the NASCAR Sprint Cup Series.  For the third time in four races, the series will race at a track of 0.75 miles or less.  This weekend's challenge: Richmond International Raceway.

This week's additional challenge: Saturday night under the lights.  Although the event marks the third consecutive week for a planned or unplanned night race, so the drivers should be used to it at this point.

Here's a look at three drivers to watch in the Toyota Owners 400:

Green Flag - Kevin Harvick

Hiccup!  That's all he experienced at Bristol as his run of 10 consecutive top-10s (dating back to last season) came to an end.  He got caught up in a wreck, and that happens at Bristol, but it wasn't before he led a race-high 184 laps.  Expect Harvick to be back to his dominating ways at Richmond where he has three career wins.

Yellow Flag - Denny Hamlin

He's led 1,390 laps at Richmond and tops the field with a 10.4 average finish at Richmond, but how's his health?  Hamlin pulled himself from the car at Bristol during the rain delay with neck and back spasms and was replaced by Erik Jones.  It might have just been the track, which is notoriously tough to drive, but it could also be signs of some lingering issues from when he suffered a broken back at Auto Club Speedway two years ago.

Red Flag - Jimmie Johnson

This is his worst track on the schedule.  He has an average finish of 17.5 at Richmond, a statistical low.  Six-Time is capable of winning anywhere and has finished first and second in the two most recent races, but making it three weeks in a row with such a finish is a tall order for him at RIR.
