Mario Williams forced a fumble when he sacked Ryan Tannehill with less than three minutes left, setting up the winning field goal to help the Buffalo Bills beat the Miami Dolphins 23-21 Sunday.
Kicker Dan Carpenter, released in August after five seasons with the Dolphins, beat his former team by making a 31-yarder with 33 seconds to go.
Rookie Nickell Robey returned an interception 19 yards for a touchdown on the third play of the game to help the Bills build an early 14-0 lead, but they had to rally after Brandon Gibson caught his second touchdown pass of the game to put Miami ahead.
The injury-plagued Bills (3-4) ended a streak of six consecutive road losses, including two this season, while Miami (3-3) lost its third game in a row.
