Earlier in London, the Kansas City Chiefs breathed fresh life into their season as they punished a poor Detroit Lions team 45-10 in Wembley’s third NFL game of the year.

Lions quarterback Matthew Stafford piled up 217 yards but was sacked six times, and picked off twice, while the Chiefs’ offence ran riot.

Quarterback Alex Smith amassed 78 yards on the ground, including a 49-yard dash in the second quarter and a touchdown run from 11 yards out. Smith also had 145 passing yards for two scores.
