The 7-6 Green Bay Packers might have help comin' their way ... a 6'3" player named ... Donald Trump.

Trump was holding a rally in Wisconsin on Tuesday when the state's political bigwigs, Paul Ryan and Gov. Scott Walker, gifted the Prez-elect a "TRUMP" Green Bay Packers jersey.

FYI -- Trump will be the 45th president of the U.S. ... hence the number.

Trump's jersey was custom-made, with his name stitched on the back. Future VP Mike Pence was also in the house ... but had to settle for an Aaron Rodgers jersey.
