Answer based on context:

The Browns traveled to London but were considered home team against the Vikings.  They scored first in the first quarter when Isaiah Crowell ran for a 26-yard touchdown (with a failed PAT) to make it 6-0.  The Vikes got on the board when Kai Forbath kicked a 35-yard field goal to make it 6-3.  The Vikes took the lead when Case Keenum found Adam Thielen on an 18-yard pass (with a failed PAT) to make it 9-3.  DeShone Kizer ran for a 1-yard touchdown to put the Browns back in the lead 13-9.  Though, the Vikes soon followed when Forbath kicked a 34-yard field goal to make it 13-12 at halftime.  In the third quarter, the Vikes retook the lead after Forbath kicked a 43-yard field goal to make it 15-13.  Zane Gonzalez then put up a 23-yard field goal to make it 16-15 in favor of the Browns retaking the lead.  Though it wouldn't last long when the Vikes retook the lead later on in the quarter when Jerick McKinnon ran for a 1-yard touchdown (with a successful 2-point conversion) to make it 23-16.  In the fourth quarter, the Vikes sealed the game when Keenum found Kyle Rudolph on a 4-yard pass to make it 30-16.  Then Forbath kicked a 51-yard field goal to make the final score 33-16. With the loss, the Browns went into their bye week 0-8. It was the 3rd time in franchise history that the Browns failed to win a regular season game in the 1st half of a season (1975, 2016).  Their 8th loss ensured that the team would fail to finish a season with a winning record for the 10th consecutive year, extending a franchise record.
