--Stewart’s Sweep Hopes End Early

--Biffle’s Night Ends in Frustration

--Labonte signs contract with Petty

-- Monkey Behind the Wheel?

--John Andretti gets Indy 500 ride

Tony Stewart’s attempt to sweep the weekends races at Darlington ended almost before it began Saturday night.

Polesitter Greg Biffle led seven times for 95 laps Saturday night at Darlington and dominated during the early part of the race.

Look for an announcement this week that Bobby Labonte has signed an agreement to remain at Petty Enterprises after 2008.

Carl Edwards has heard enough about the positioning of the rear-end housing on his No. 99 Ford. Other drivers have noticed that Edwards' car has a different attitude as it circles the track, specifically that it's more "yawed out" than other cars, giving the appearance that the rear end is sliding out.

John Andretti will attempt to qualify for his ninth Indianapolis 500 in the No. 24 Roth Racing car. Andretti, who started 24th and finished 30th last year in a Panther Racing-prepared car in his first Indy 500 since 1994, will replace Jay Howard in the seat for the race.
