‘Smoke’ fired up: Stewart curses Dale Jr.’s name over in-car radio

In case you missed it, there was a not-so-little disagreement between Dale Earnhardt Jr. and Tony Stewart on Sunday at Richmond International Raceway.

Jockeying for position inside the top 10 with fewer than 50 laps left in the Toyota Owners 400, the two veteran drivers made contact that resulted in Stewart spinning into the inside retaining wall and being unable to continue when his car refused to refire.

Earnhardt, meanwhile, went on to finish 14th, and afterward refused to take responsibility for the incident — an incident that left Stewart steaming mad.

How angry was Stewart?

After returning to the garage area, the three-time Sprint Cup champion hastily tossed his helmet and HANS device into the No. 14 hauler and then refused to speak with reporters.
