NASCAR: Harvick, Johnson spar following Chicagoland

The onset of the Chase for the Sprint Cup always magnifies the significance – and emotional reactions – to on-track incidents, and so it was again following Sunday's opening Chase round at Chicagoland.

After his mid-race contact with Jimmie Johnson was followed by Kevin Harvick crashing out with a blown tire four laps later, dealing a hefty blow to his chances of retaining his championship crown, the confrontation caught below between the two in the motor coach lot following the race. An "exchange of views" led to a shove from Harvick before he was restrained by his business manager, Josh Jones.
