There was an ugly three-car clang at the start of NASCAR Sprint Cup Series practise Friday morning Dover International Speedway.

Just six minutes into practice, a gear appeared to break on Danica Patricks No. 10 Stewart-Haas Racing Chevrolet. Patrick spun at the depart of Turn 4 as her car dropped oil onto the way and caught fire.

Behind Patrick, her teammate Tony Stewart stumbled the lubricant, as did the Chip Ganassi-owned Chevrolet of Jamie McMurray. Both of them had hard contact with the wall, while Patricks car remained igniting as it extended around on the frontstretch.

Stewart, which continued to nursing an injured back, told his team on the radio, That hurt. The three-time champ had three separate impacts, the first coming where there was no SAFER barrier.

All three motorists were able to clamber from their respective cars, but McMurray eventually left the infield caution core cradling his left forearm in the elbow expanse, in obvious pain.

I got back to the throttle and it was like a muted — actually stifled like I blew an machine, said Patrick. And then it just got sideways and thump the wall. As you can see, theres lots of flares, very. Obviously, some kind of lubricant of something like that in there that developed that.

I genuinely feel bad because Jamies shoulder injured pretty bad and I dont know if Tonys feeling perfect, said Patrick. Definitely unfortunate. Not something we usually see.

Patrick expressed briefly with Stewart after the crash. I fantasize at any point in time you worry for Tony, simply made to ensure that hes OK after everything hes are going through physically. Hopefully, hes alright, but I guess merely he knows how he experiences right now.
