Big shakeup at Penske

Last week, Steve Addington came over from Penske Racing's 22 car to replace Darian Grubb on the #14 car driven by now 3-time champion Tony Stewart. That was just the beginning.

Due to an incident at Homestead-Miami involving ESPN pit reporter Dr. Jerry Punch and pressure from sponsors Shell, Pennzoil, and Dodge, Kurt Busch and Roger Penske parted ways on Monday, leaving Penske Racing with only one driver, Brad Keslowski in the #2 car, unless a replacement driver can be found.

This adds another wrinkle in the yearly "silly season" tradition for 2012, adding Brian Vicker's unknown future with Red Bull shutting down it's NASCAR operations after 2011, among others.
