BROOKLYN, Mich. -- Kyle Busch checked out of the infield care center with his body and sarcasm intact after a wreck in final NASCAR Sprint Cup Series practice Saturday at Michigan International Speedway tore up his No. 18 Toyota that qualified sixth on Friday.
Busch and the No. 18 team will run their backup car, dropping to the back of the field for the start of Sunday's Pure Michigan 400 (2:30 p.m. ET, NBCSN, MRN, SiriusXM).
Busch, a longstanding critic of grass infields, had little to say about his health after the wreck early in practice in which he appeared to get loose when in close proximity to Clint Bowyer's No. 15 Toyota, assuring fans "I'm fine."
But he had a lot to say about the damage to his car.
"I'm thinking all these race tracks need more grass. I think more grass would be beneficial," Busch said sarcastically. "I think we should have more grass and it should be tall."
Grass is akin to ice when a race car careens across it, and damage to the car that results from ripping up chunks of turf often could be avoided, drivers say.
Busch was even a bit more colorful about grass at tracks on Twitter.
"I was just running along, everything was fine and I was actually feeling pretty good about it. Just started to get a little free up off of (Turn 4)," Busch said. "It started stepping out like it did here in the spring. I over-corrected and hit the wall so this time around I just kind of made it keep rotating and head down toward the infield. I think we need more grass at these race tracks, I think the apron should be full of grass."
Busch's biggest concern with gong to a backup car piled on top of the challenge of running a new package, the high-drag package, at Michigan is he must avoid a bad finish to retain his Chase eligibility. Busch has the required win -- in fact four of them -- but also must maintain a 30th-or-better place in the drivers points standings.
After a runner-up finish at Watkins Glen, Busch sits in 30th place in the standings, six points ahead of 31st-place driver Cole Whit.

For the purpose of avoiding a disastrous finish Sunday, Busch said wrecking Saturday was a good thing, because he learned what not to do with this high-drag rules package.
"We just learned about how the draft was and what kind of instances you could try to put yourself in and what kind of instances you didn't want to be in," he said. "Now that we have to start in the back, it's a good thing we did that. It's a good exercise and we'll just have to adjust our car for being in the back of the field."
After returning to practice, Busch posted the ninth-best practice speed of 190.320 mph in the backup No. 18 Toyota.
