The action came for his use of what NASCAR called, "inappropriate language," following the Sam's Town 300.
The use of profanity is prohibited under NASCAR rules, a fact stressed to drivers in meetings last month with NASCAR president Mike Helton. But Sauter ran afoul Saturday during a post-race radio interview in which he blasted Michael Waltrip for causing a late accident.
Sauter posted an apology on his website.
"There's absolutely no excuse for what I said. I truly regret the way I handled myself and it won't happen again," he said.
The deduction of points dropped Sauter from second to fourth in the Busch standings, 95 points behind leader Kevin Harvick.
