No, Jared Goff's knee being down during Dan Campbell's gutsy 4th down call wasn't missed by refs
Instead of kicking the field goal with the game tied and the Lions facing 4th-and-inches, he kept the offense on the field and called for David Montgomery to run it for a first down and THEN kick the field goal. It worked, but it almost didn’t when QB Jared Goff stumbled yet somehow got the ball into Montgomery’s hands.
