Q: Passage: Week 10 featured the top-ranked defenses (by yardage against) in each conference, as the Lions hosted the Dolphins. Detroit got off to a quick start. Matt Prater kicked a 26-yard field goal on the opening drive of the game. Later in the first quarter, Calvin Johnson, playing in his first game since Week 5, caught a 49-yard TD pass from Matthew Stafford for a 10-0 lead. Miami managed a 23-yard Caleb Sturgis field goal before halftime, making the score 10-3. The Dolphins took the lead in the third, starting with a 50-yard Stugis field goal.

On the next play, Ryan Tannehill connected with Mike Wallace for the touchdown, putting Miami ahead, 13-10. Prater made good on a 50-yard field goal early in the fourth quarter to knot the score at 13-13, but Sturgis' 20-yarder put Miami back on top by 3.
