Dolphins stay undefeated by edging Buffalo

What happened: The Fins survived a high-powered Bills offense, an injury scare to Miami quarterback Tua Tagovailoa and a botched "butt punt" that brought Buffalo within two points with under two minutes left.

• Tagovailoa went into concussion protocol after a late hit on a throw that temporarily took him out of the game, but he returned in the second half.
• Miami was outmatched on offense, but its defense stepped up late in the game with a goal-line stand.
• With under two minutes left, and backed into his own end zone, Miami punter Thomas Morstead kicked the ball into the butt of his blocker and out of bounds, causing a safety.
• The Bills drove down the field but ran out of time trying to set up a potential game-winning field goal.”

What they're saying: Adam Beasley, NFL director for Pro Football Network, tweeted that it was the "best, most rewarding Dolphins win in a generation."

What's next: The Fins play the Bengals in Cincinnati on Thursday after a short week.
