Kurt Busch's future with Phoenix Racing is in jeopardy after NASCAR suspended the 2004 Sprint Cup champion for this weekend's race at Pocono Raceway.

Busch was suspended for threatening comments made to Sporting News reporter Bob Pockrass following Saturday's Nationwide Series race at Dover International Speedway.

Busch was already on probation for a May 12 incident with Ryan Newman in a Sprint Cup race at Darlington. His suspension runs through June 13, meaning he will be eligible to return for the June 17 race at Michigan.

In a statement, Busch said: "I accept NASCAR's decision. I put them in a box, they had to take action and it's my fault for putting them in this position. I apologize for the comments I made to Bob Pockrass."

Phoenix Racing owner James Finch isn't so sure the driver will return immediately after serving the suspension, saying he will sit down with Busch over the next couple of days to see if they will move forward together.

"If he's going to kill himself I'm not going to be in the airplane with him," Finch told ESPN.com by phone. "If that's what he's planning on doing, I am going to get out."

Finch said he was in the process of looking for a driver to replace Busch for Pocono and possibly beyond. Among the candidates he mentioned were Brian Vickers and David Reutimann, although Reutimann was scheduled to drive the No. 10 for Tommy Baldwin Racing this weekend.
