Haas team could lose sponsors

With NASCAR's falling attendance and falling TV ratings, some teams are having a hard time convincing their existing sponsors to renew. Haas CNC Racing has settled on its drivers for its two-car Sprint Cup team in 2008, but its sponsorship situation is unsettled.

Best Buy, which backs the team's No. 66 – driven for the first time this weekend by Jeremy Mayfield – has not decided its future, a spokesman for the company said this week.

And Wednesday, a statement released by Yellow Transportation said that company is evaluating its future in the sport. Yellow entered Nextel Cup this season as sponsor of Johnny Sauter's No. 70.
