To celebrate the score, St. Brown found some Lions fans seated in the first row and did a "Lambeau Leap" into the stands. But while he was in the crowd, a Packers fan reached over and dumped beer on St. Brown's helmet.
St. Brown's second touchdown of the season helped the Lions take an early 7-3 lead over their NFC North rival. It also started a stretch of 27 unanswered for Detroit as it took a commanding 27-3 lead into halftime.
