Jared Goff threw three touchdown passes and the Lions tuned up for their Week 18 division showdown against Minnesota by beating the 49ers 40-34 on Monday night.
San Francisco was eliminated from playoff contention last week and Detroit plays Minnesota in the regular-season finale next week, with the winner earning the NFC North title and top seed in the NFC playoffs, and the loser relegated to being the first 14-win wild-card team in NFL history.
Jahymr Gibbs put the game away with a 30-yard touchdown run with less than three minutes left following Purdy’s second interception, giving him 117 yards on the night.
