Driver Kyle Busch is feeling more heat.  This time from a major sponsor.

FOX News Radio's Marghiee "Trackside" Teshineh has the story:

It was a crash that may cost Kyle Busch a place at the season finale of this year's chase.  One of his sponsors, Z-Line Designs, would like to see Busch yanked for the last Nationwide race at Homestead and replaced with another driver.  And whether Busch drives in the last two Sprint Cup races is now in question.  This comes after Busch was fined $50,000 and benched from the weekend Sprint Cup and Nationwide races at Texas after wrecking Ron Hornaday's car during a Friday truck series race while under caution.  Busch had been a contender for the cup this year, but is now mathematically out of contention.
