And there's potentially even more good news on the horizon.
Gailey said there's a good chance both running back Fred Jackson and defensive end Chris Kelsay will be cleared for practice by Wednesday. Jackson did not play against Miami because of a concussion, while Kelsay has missed the past two games with a neck injury.
That doesn't mean the Bills lack concerns.
It starts with an offense that's been inconsistent in scoring touchdowns. Their lone touchdown against Miami came 90 seconds in, when Leodis McKelvin scored on a 79-yard punt return.
The Bills never reached the end zone again despite producing 204 yards of offense in the first half. They stalled four times inside the Dolphins 20, with Rian Lindell hitting four field-goal attempts, the longest from 42 yards.
"It doesn't really matter because we got the win," receiver Stevie Johnson said. "But I think we could've showed how powerful our offense could be. ... I felt like we could've beaten them by more points."
The lack of finish has become a trend.
In its past seven games, Buffalo's scored eight touchdowns and settled for 10 field goals on 22 trips inside an opponent's 20. That includes the Bills scoring four TDs on seven red-zone possessions in a 37-31 loss at New England last weekend.
Quarterback Ryan Fitzpatrick credited the Dolphins' defense for playing well, and noted that it was difficult to prepare a full game plan with only three days of practice.
"Yesterday, there's some stuff we have to look at and correct," Fitzpatrick said.
He'll still take the win.
"It's a rosier day, today," Fitzpatrick said. "There's more sunshine in here today than there's been the last few weeks. It makes everybody feel better."
