Noteworthy: The Dolphins own an 8-1 record in games played inside Hard Rock Stadium where coach Adam Gase is calling plays for Ryan Tannehill during their run together, and average 15 points more at home than on the road. … A win would give Miami a victory in their first three games at home since 2002. … The Dolphins are

16-5 in one-score games (eight-point margin or less) in the Gase era. … Defensive end Charles Harris will likely start his second game of the season if Cameron Wake can’t play. … The Bears feature the NFL’s best run defense, holding opponents to 64.0 rushing yards per game. … Chicago quarterback Mitch Trubisky, who was the first pick in the 2017 draft, is completing 70 percent of his passes, and is coming off a performance where he threw six touchdowns in a

48-10 win over Tampa Bay. Trubisky has a 92.8 passer rating on third down throws this season. … The Bears are averaging 116 rushing yards per game, and 4.2 yards per carry.
