Kyle Busch is apparently expecting retaliation from Brad Keselowski for wrecking him in the Nationwide Series race last week at Kansas.

Busch told SiriusXM NASCAR on Friday that Keselowski is "stupid enough" to retaliate for an incident between the two last Saturday. They were racing side-by-side in the closing laps when contact by Busch sent Keselowski's car into the wall.

Keselowski jumped from his car and jogged toward pit road, gesturing at Busch's crew. He accused Busch of being a dirty driver and hinted he can retaliate because he's not racing for the Sprint Cup championship.

Busch said Friday on Sirius that Keselowski started this feud last year at Watkins Glen, and if he acts again, "that will just bring on a heck of a lot more fireworks."
