Griffin had seen enough after Bradford started the game 5-of-11 for 36 passing and was sacked four times:

Gotta get Bradford out for his own safety trust me I know the feeling2017-10-10 01:44:57
Case Keenum replaced Bradford with 25 seconds left in the first half.
Bradford started despite suffering from a knee injury that had kept him out since Week 1. Griffin wasn't the only person who thought the knee remained an issue for Bradford:

At this point, Bradford could be hopping on one leg and he'd still be out there. What more does Zimmer need to see?2017-10-10 01:44:45

Bradford must have major knee issues. Get him out2017-10-10 01:46:39

Bradford can't even put weight on that leg. You got to take yourself out. Or the coaches have to see it.2017-10-10 01:46:23
Few players know the dangers of playing through an injury better than RG3.
He stayed on the field despite looking less than 100 percent in the Washington Redskins' wild-card matchup with the Seattle Seahawks in January 2013. Griffin eventually suffered a gruesome knee injury that proved to be a partially torn ACL and MCL.
Griffin never recaptured the dynamism he displayed in his rookie season.
It's doubtful playing Monday night will result in similar long-term damage to Bradford's NFL career, but it didn't take long to see he wasn't himself and needed to stand on the sideline while Keenum took the reins of the Minnesota offense.
