Terry Bradshaw is sticking up for the Philadelphia Eagles ... telling TMZ Sports he supports their decision to not go to the White House -- saying, "1st Amendment rights, I totally believe in it."
The "FOX NFL Sunday" star didn't mince his words when we asked about the issue -- telling us, "I agree with the Eagles. Totally. 100 percent."
When asked about Donald Trump specifically, Bradshaw said ... "Trump just needs to ... he just needs to go somewhere and enjoy the money he's got."
Bradshaw continued ... "You know what's so bad about that whole event? Was how they were portrayed as protesting, kneeling, during the national anthem when they were praying. That is just wrong."
For the record, FOX News issued a statement after that incident -- saying, "We apologize for the error."
