NASCAR has confirmed that a major partner announcement will be made today at the Michigan International Speedway at 1 p.m. ET.The announcement comes during the NASCAR Truck and Cup Series race weekend in Michigan and will be made ahead of the Cup Series FireKeepers Casino 400, which begins at 2 p.m. ET.It stated in a media alert that, "A major NASCAR partner announcement will be made on the pre-race stage at Michigan International Speedway for fans and media in attendance."Although it has not been confirmed what the announcement will be, many expect it to be to confirm the return of Dodge RAM as a manufacturer to the Craftsman Truck Series.If the iconic American car brand returns to the sport, it will be the first time a RAM has raced in the Truck Series since 2016.Commissioner of NASCAR Steve Phelps previously explained to Sports Business Journal:"We are having robust discussions with a number of [original equipment] partners that someday, if I had to guess and were a betting man, something is going to hit."I just don't know with whom or the timing of that. I know that's an answer I've given repeatedly over the last five years, but they're facts. There's no BS in the comment I just made."If this is true, Dodge RAM would join Toyota, Chevrolet, and Ford as the fourth OEM in the racing series.On top of the rumors of Dodge returning to the Truck Series, there is also speculation that YouTuber turned racer Cleetus McFarland (Garrett Mitchell) could be racing with the team.NASCAR Cup Series FireKeepers Casino 400: Starting Grid Chase Briscoe Denny Hamlin William Byron Kyle Larson Chris Buescher Bubba Wallace Austin Cindric Tyler Reddick Ryan Blaney Carson Hocevar Joey Logano Alex Bowman Chase Elliott AJ Allmendinger Ross Chastain John H.
