Here's a rundown of the Sprint Cup drivers who will most likely be switching teams for the 2009 season:

Mark Martin confirmed Friday that he will give up his duties driving the No. 8 car for Dale Earnhardt Inc. to drive the No. 5 car full-time next season for Hendrick Motorsports. A four-time Series runner-up, Martin will take one last shot at winning the Cup title before splitting the 2010 season with a driver to be named. Brad Keselowski, driver of the No. 88 in the Nationwide Series, is an option. Martin, 49, almost won last year's Daytona 500 with Ginn Racing, before Kevin Harvick beat him to the line, so he has shown he can still be a very competitive and a winning race car driver. This may be his best shot at winning a Cup title.

Casey Mears will be leaving the No. 5 car at the end of this season due to inconsistency on the track and a lack of results from the team. Mears finished 15th in the points standings last year with Hendrick's No. 25 team, who are now part of Dale Earnhardt Jr.'s No. 88 team, and won the Coca-Cola 600 with them. Once he finds a team Mears will be in his fifth program in as many years, starting his career with Chip Ganassi Racing in the No. 41 and 42 cars before joining Hendrick last season. Mears has been linked to the fourth driver team of Richard Childress Racing that will start next season and a possible opening at Joe Gibbs Racing where Tony Stewart may leave at the end of this season. Mears is the best driver with the worst luck in the Cup Series, but he'll land on his feet somewhere and get the support he needs.

Dario Franchitti's No. 40 team has been shut down by Ganassi Racing because of lack of funding. The team cited "lack of sponsorship funding", for cutting the No. 40 team which resulted in 71 layoffs. Ganassi officials have said that they are "committed to Franchitti's continued stock-car development." Franchitti has missed five races this season due to a broken ankle at the Nationwide Talladega race. Franchitti is set to speak with Chip Ganassi next week concerning his future, which could include the former IndyCar champ to race in the Nationwide Series for the rest of the season.

Tony Stewart has reached an agreement with Office Depot to be the sponsor of his car if he can finalize a deal with Haas CNC Racing to become a part-owner/driver with the team. The two-time Cup champion has been in serious talks with both Haas since early this season, furthering speculation that he will want to be released from the last year of his contract with Gibbs Racing. An announcement could be made as soon as the July 27 race at Indianapolis Motor Speedway, near Stewart's hometown of Columbus, Ind. Stewart would need an official release from his deal with Gibbs, before he can move to another team. JD Gibbs has said that the organization might be willing to start a fourth team to make room for 18-year-old phenom Joey Logano.
