David Reutimann is replacing the suspended Kurt Busch behind the wheel of Phoenix Racing's number-51 car for Sunday's race at Pocono. Busch was suspended Monday for threatening comments towards a reporter following Saturday's Nationwide Series race at Dover. Busch was already on probation for a prior incident at Darlington last month. He's eligible to return a week from Wednesday, but his long-term future with Phoenix Racing could be in jeopardy
